EN/UVLO 1 I EN/UVLO input. A voltage on this pin above 1.24V enables normal operation. Forcing this pin below 0.3V shuts down the device reducing quiescent current to approximately 1.5µA (typical). Optionally connect to the input supply through a resistive divider to set the undervoltage lockout. When EN/UVLO is left floating an internal pull down of 100nA pulls EN/UVLO low and keeps the device in shutdown state. OV 2 I Adjustable overvoltage threshold input. Connect a resistor ladder from input supply, OV to GND. When the voltage at OVP exceeds the overvoltage cut-off threshold then the PD is pulled down to SRC turning OFF the external FET. When the voltage at OV goes below OV falling threshold then PU gets pulled up to BST, turning ON the external FET. OV must be connected to GND when not used. When OV is left floating an internal pull down of 100nA pulls OV low and keeps PU pulled up to BST. INP 3 I Input signal for external discharge FET control. CMOS compatible input reference to GND that sets the state of PD and PU pins. INP has an internal weak pull down of 100nA to GND to keep PD pulled to SRC when INP is left floating.

7.3 Feature Description
7.3.1 Charge Pump and Gate Driver Output (VS, PU, PD, BST, SRC)
Figure 7-1 shows a simplified diagram of the charge pump and gate driver circuit implementation. The device houses a strong 1.69-A/2-A peak source/sink gate driver (PU, PD) for driving power FET. The strong gate drivers enable paralleling of FETs in high power system designs ensuring minimum transition time in saturation region. A 11-V, 345-µA charge pump is derived from VS terminal and charges the external boot-strap capacitor, C BST that is placed across the gate driver (BST and SRC). VS is the supply pin to the controller. With VS applied and EN/UVLO pulled high, the charge pump turns ON and charges the CBST capacitor. After the voltage across C BST crosses V(BST_UVLOR), the GATE driver section is activated. The device has a 1-V (typical) UVLO hysteresis to ensure chattering less performance during initial GATE turn ON. Choose C BST based on the external FET Q G and allowed dip during FET turn-ON. The charge pump remains enabled until the BST to SRC voltage reaches 11.8 V, typically, at which point the charge pump is disabled decreasing the current draw on the VS pin. The charge pump remains disabled until the BST to SRC voltage discharges to 10 V typically at which point the charge pump is enabled. The voltage between BST and SRC continue to charge and discharge between 11.8 V and 10 V as shown in the Figure 7-2.

7.3.2 Capacitive Load Driving Using FET Gate (PU, PD) Slew Rate Control
Certain end equipments like automotive power distribution unit power different loads including other ECUs. These ECUs can have large input capacitances. If power to the ECUs is switched on in uncontrolled way, large inrush currents can occur potentially damaging the power FETs. To limit the inrush current during capacitive load switching, the following system design technique can be used with TPS12000-Q1. For limiting inrush current during turn ON of the FET with capacitive loads, use R 1, R2, C1 as shown in Figure 7-4. The R1 and C1 components slow down the voltage ramp rate at the gate of the FET. The FET source follows the gate voltage resulting in a controlled voltage ramp across the output capacitors. BST SRC PU PD Level ShifterINP CBST TPS12000-Q1 CLOAD Figure 7-4. Inrush Current limiting Use the Equation 2 to calculate the inrush current during turn-ON of the FET.

C 1 = 0.63 × V B ST − SRC × C LOAD R 1 × I INRUSH (3) Where, CLOAD is the load capacitance, VBATT is the input voltage and Tcharge is the charge time, V(BST-SRC) is the charge pump voltage (11 V), Use a damping resistor R2 (~ 10 Ω) in series with C1. Equation 3 can be used to compute required C1 value for a target inrush current. A 100 kΩ resistor for R1 can be a good starting point for calculations. Connecting PD pin of TPS12000-Q1 directly to the gate of the external FET ensures fast turn OFF without any impact of R1 and C1 components. C1 results in an additional loading on C BST to charge during turn-ON. Use below equation to calculate the required CBST value: C B ST = Q g t ot a l ∆ V BST + 10 × C 1 (4) Where, Qg(total) is the total gate charge of the FET. ΔVBST (1 V typical) is the ripple voltage across BST to SRC pins.
7.3.3 Short-Circuit Protection
The TPS12000-Q1 feature adjustable short circuit protection. The threshold and response time can be adjusted using RISCP resistor and CTMR capacitor respectively. The device senses the voltage across CS+ and CS– pins. These pins can be connected across an external high and low side current sense resistor (R SNS) as or across the FET drain and source terminals for FET R DSON sensing shown in Figure 7-5 , Figure 7-6 , Figure 7-7 and Figure 7-8 respectively.

TPS12000-Q1 Application Circuit With External Sense Resistor RSNS on Based Low Side Current Sensing on Load Side Set the short-circuit detection threshold using an external R ISCP resistor across ISCP and GND pins. Use Equation 5 to calculate the required RISCP value: R ISCP Ω = I SC × R SNS − 10 mV 2 µ A (5) Refer to Equation 9 in Section 8.1.1 section for update in equation in final revision of IC. Where, RSNS is the high or low side current sense resistor value or the FET RDSON value. ISC is the desired short circuit current level. The short circuit protection response is fastest with no CTMR cap connected across TMR and GND pins. With device powered ON and EN/UVLO, INP pulled high, During Q 1 turn ON, first VGS of external FET is sensed by monitoring the voltage across PD to SRC. Once PD to SRC voltage raises above V (G_GOOD) (7.5 V typical) threshold which ensures that the external FET is enhanced, then the SCP comparator output is monitored. If the sensed voltage across CS+ and CS– exceeds the short-circuit set point (V SCP), PD pulls low to SRC and FLT asserts low. Subsequent events can be set either to be auto-retry or latch off as described in following sections. VGS of external FET (Q 1) is only monitored when CS_SEL is pulled low. VGS of external FET (Q 1) is not monitored for low side current sensing as shown Figure 7-7 and Figure 7-8.
7.3.3.1 Short-Circuit Protection With Auto-Retry
The CTMR programs the short-circuit protection delay (t SC) and auto-retry time (t RETRY). Once the voltage across CS+ and CS– exceeds the set point, the CTMR starts charging with 80-μA pull-up current. After C TMR charges to V (TMR_SC), PD pulls low to SRC and FLT asserts low providing warning on impending FET turn OFF. Post this event, the auto-retry behavior starts. The C TMR capacitor starts discharging with 2.5-uA pulldown current. After the voltage reaches V (TMR_LOW) level, the capacitor starts charging with 2.2-uA pullup. After 32 charging-discharging cycles of CTMR the FET turns ON back and FLT de-asserts. The device retry time (tRETRY) is based on CTMR for the first time as per Equation 7. Use Equation 6 to calculate the CTMR capacitor to be connected across TMR and GND. TPS1200-Q1 SLUSEZ3 – DECEMBER 2023 www.ti.com ADVANCE INFORMATION

7.3.3.2 Short-Circuit Protection With Latch-Off
Connect an approximately 100-k Ω resistor across C TMR as shown in .

On the output side, the device can see transient negative voltages during regular operation due to output cable harness inductance kickbacks when the switches are turned OFF. In such systems, the output negative voltage level is limited by the output side TVS or a diode.
7.3.6 Short-Circuit Protection Diagnosis (SCP_TEST)
In the safety critical designs, short-circuit protection (SCP) feature and its diagnosis is important. The TPS12000-Q1 features the diagnosis of the internal short circuit protection. When SCP_TEST is driven low to high then, a voltage is applied internally across the SCP comparator inputs to simulate a short circuit event. The comparator output controls the gate drive (PU/PD) and also the FLT. If the gate drive goes low (with initially being high) and FLT alos goes low then it indicates that the SCP is good otherwise it is to be treated as SCP feature is not functional. If the SCP_TEST feature is not used, then connect SCP_TEST pin to GND.

7.4 Device Functional Modes
The TPS12000-Q1 has two modes of operation. Active mode and low IQ shutdown mode. If the EN/UVLO pin voltage is greater than V (ENR) rising threshold, then the device is in active mode. In active state the internal charge pump is enabled, gate drivers, all the protection and diagnostic features are enabled. If the EN/UVLO voltage is pulled below V (ENF) falling threshold, the device enters into low IQ shutdown mode. In this mode, the charge pump, gate drivers and all the protection features are disabled. The gate drive and external FETs turn OFF. The TPS12000-Q1 consumes low IQ of 1.5 μA (typical) in this mode. www.ti.com TPS1200-Q1 SLUSEZ3 – DECEMBER 2023 ADVANCE INFORMATION Copyright © 2024 Texas Instruments Incorporated Submit Document Feedback 17 Product Folder Links: TPS1200-Q1
8 Application and Implementation
Information in the following applications sections is not part of the TI component specification, and TI does not warrant its accuracy or completeness. TI’s customers are responsible for determining suitability of components for their purposes, as well as validating and testing their design implementation to confirm system functionality.
8.1 Application Information
The TPS12000-Q1 is a 45-V low IQ smart high side driver with protection and diagnostics. With wide operating voltage range of 3.5 V–40 V, the device is suitable for 12-V system designs. The device can withstand and protect the loads from negative supply voltages down to –40 V. It has strong 1.69-A/2-A peak source/sink gate driver enabling power switching using parallel FETs in high current system designs. The device provides configurable short circuit protection using ISCP and TMR pins for adjusting the threshold and response time respectively. Auto-retry and latch-off fault behavior can be configured. With TPS12000-Q1, current sensing can be done either by an external sense resistor or by MOSFET VDS sensing. High or low side current sense resistor configuration is possible by using CS_SEL pin input. Diagnosis of the integrated short circuit comparator can be done using external control on SCP_TEST input.The device indicates fault (FLT) on open drain output during during short circuit and input under voltage conditions. It also have a dedicate fault indication (FLT_GD) to indicate the gate drive UVLO condition. Low Quiescent Current 43-µA operation enables always ON system designs. Quiescent current reduces to 1.5 μA (typical) with EN/UVLO low.
8.1.1 Application Limitations
This section highlights some limitations in the application which were identified during bench evaluation of the existing TPS12000-Q1 silicon on the evaluation module (EVM).
8.1.1.1 Short-Circuit Protection Delay
In application designs with high side current sense configurations as shown in Figure 7-5 and Figure 7-6 with CTMR = Open, the short-circuit protection delay during power up with output short circuited does not match the specified maximum value of 10 μs. Testing has shown that the actual short-circuit protection delay during power up by EN/UVLO signal is < 13 μs. A design fix must be included in the final version of the IC.
8.1.1.2 Short-Circuit Protection Threshold
The minimum short-circuit protection threshold is limited to 30 mV. A design update is planned in the final revision of the IC to extend the minimum threshold down to 20 mV. Due to the design update there will be a change of RSCP resistor formula and the revised formula will be as per the Equation 9. R ISCP Ω = I SC × R SNS − 19 mV 2 µ A (9) Lowest SCP threshold setting will be limited to 20 mV. TPS1200-Q1 SLUSEZ3 – DECEMBER 2023 www.ti.com ADVANCE INFORMATION

8.2.2 Detailed Design Procedure
Selection of MOSFET, Q1 For selecting the MOSFET Q 1, important electrical parameters are the maximum continuous drain current I D, the maximum drain-to-source voltage VDS(MAX), the maximum drain-to-source voltage VGS(MAX), and the drain-to- source ON resistance RDSON. The maximum continuous drain current, ID, rating must exceed the maximum continuous load current. The maximum drain-to-source voltage, V DS(MAX), must be high enough to withstand the highest voltage seen in the application. Considering 35 V as the maximum application voltage due to load dump, MOSFETs with V DS voltage rating of 40 V is chosen for this application. The maximum V GS TPS12000-Q1 can drive is 11 V, so a MOSFET with 15-V minimum V GS rating must be selected. To reduce the MOSFET conduction losses, an appropriate RDS(ON) is preferred. Based on the design requirements, BUK7J1R4-40H is selected and its ratings are:
- 40-V VDS(MAX) and ±20-V VGS(MAX)
- RDS(ON) is 1.06-mΩ typical at 10-V VGS
- MOSFET Qg(total) is 73 nC typical TI recommends to make sure that the short-circuit conditions such max V IN and ISC are within SOA of selected FET (Q1) for at-least > tSC timing. Selection of Bootstrap Capacitor, CBST The internal charge pump charges the external bootstrap capacitor (connected between BST and SRC pins) with approximately 345 μA. Use the following equation to calculate the minimum required value of the bootstrap capacitor for driving BUK7J1R4-40H MOSFET C B ST = Q g t ot a l
1 V = 73 nF (10)
Choose closest available standard value: 100 nF, 10 %. Programming the Short-Circuit Protection Threshold – RISCP Selection The RISCP sets the short-circuit protection threshold, whose value can be calculated using below equation: R ISCP Ω = I SC × R DS _ ON − 10 mV 2 µA (11) Refer to Equation 9 in Section 8.1.1 section for update in equation in final revision of IC. To set 100 A as short-circuit protection threshold, RISCP value is calculated to be 45 kΩ. Choose the closest available standard value: 45.2 kΩ, 1%. In case where large di/dt is involved, the system and layout parasitic inductances can generate large differential signal voltages between CS+ and CS- pins. This action can trigger false short-circuit protection and nuisance trips in the system. To overcome such scenario, TI suggests to add placeholder for RC filter components across sense resistor (R SNS) and tweak the values during test in the real system. The RC filter components should not be used in current sense designs by MOSFET VDS sensing to avoid impact on the short-circuit protection response.

Programming the Fault timer Period – CTMR Selection For the design example under discussion, overcurrent transients are allowed for 50- μs duration. This blanking interval, tSC (or circuit breaker interval, TCB) can be set by selecting appropriate capacitor C TMR from TMR pin to ground. The value of CTMR to set 50 μs for tSC can be calculated using following equation: C TM R = 80 µA × t SC 1.1 (12) Choose closest available standard value: 3.3 nF, 10 %. Setting the Undervoltage Lockout and Overvoltage Set Point The undervoltage lockout (UVLO) and overvoltage set point are adjusted using an external voltage divider network of R 1, R 2 and R 3 connected between VS, EN/UVLO, OV and GND pins of the device. The values required for setting the undervoltage and overvoltage are calculated by solving Equation 13 and Equation 14. V(OVR) = R3 × VINOVP (R1 + R2 + R3) (13) V(UVLOR) = R2 + R3 × VINUVLO (R1 + R2 + R3) (14) For minimizing the input current drawn from the power supply, TI recommends to use higher values of resistance for R1, R2 and R3. However, leakage currents due to external active components connected to the resistor string can add error to these calculations. So, the resistor string current, I(R 123) must be chosen to be 20 times greater than the leakage current of UVLO and OV pins. From the device electrical specifications, V (OVR) = 1.24 V and V (UVLOR) = 1.24 V. From the design requirements, VINOVP is 36 V and VIN UVLO is 6.5 V. To solve the equation, first choose the value of R 1 = 470 k Ω and use Equation 13 to solve for (R2 + R3) = 108.3 kΩ. Use Equation 14 and value of (R2 + R3) to solve for R3 = 19.6 kΩ and finally R2 = 88.7 kΩ. Choose the closest standard 1 % resistor values: R 1 = 470 kΩ, R2 = 88.7 kΩ, and R3 = 19.6 kΩ. www.ti.com TPS1200-Q1 SLUSEZ3 – DECEMBER 2023 ADVANCE INFORMATION Copyright © 2024 Texas Instruments Incorporated Submit Document Feedback 21 Product Folder Links: TPS1200-Q1

8.3 Power Supply Recommendations
When the external MOSFETs turn-OFF during the conditions such as INP1 control, overcurrent protection causing an interruption of the current flow, the input parasitic line inductance generates a positive voltage spike on the input and output parasitic inductance generates a negative voltage spike on the output. The peak amplitude of voltage spikes (transients) depends on the value of inductance in series to the input or output of the device. These transients can exceed the Section 5.1 of the device if steps are not taken to address the issue. Typical methods for addressing transients include:
- Use of a TVS diode and input capacitor filter combination across input to and GND to absorb the energy and dampen the positive transients.
- Use of a diode or a TVS diode across the output and GND to absorb negative spikes. The TPS12000-Q1 gets powered from the VS pin. Voltage at this pin must be maintained above V(VS_PORR) level to ensure proper operation. If the input power supply source is noisy with transients, then TI recommends to place a RVS – CVS filter between the input supply line and VS pin to filter out the supply noise. TI recommends RVS value around 100 Ω. In case where large di/dt is involved, the system and layout parasitic inductances can generate large differential signal voltages between CS+ and CS– pins. This action can trigger false short-circuit protection and nuisance trips in the system. To overcome such scenario, TI suggests to add placeholder for RC filter components across sense resistor (R SNS) and tweak the values during test in the real system.

8.4 Layout
8.4.1 Layout Guidelines
- Place the sense resistor (RSNS) close to the TPS12000-Q1 and then connect RSNS using the Kelvin techniques. Refer to Choosing the Right Sense Resistor Layout for more information on the Kelvin techniques. For VDS based Current Sensing, follow the same kevlin techniques across the MOSFET.
- Choose a 0.1 µF or higher value ceramic decoupling capacitor between VS terminal and GND for all the applications. Consider adding RC network at the supply pin (VS) of the controller to improve decoupling against the power line disturbances.
- Make the high-current path from the board input to the load, and the return path, parallel and close to each other to minimize loop inductance.
- Place the external MOSFETs close to the controller GATE drive pins (PU/PD) such that the GATE of the MOSFETs are close to the controller GATE drive pins and forms a shorter GATE loop. Consider adding a place holder for a resistor in series with the Gate of each external MOSFET to damp high frequency oscillations if need arises.
- Place a TVS diode at the input to clamp the voltage transients during hot-plug and fast turn-off events.
- Place the external boot-strap capacitor close to BST and SRC pins to form very short loop.
- Connect the ground connections for the various components around the TPS12000-Q1 directly to each other, and to the TPS12000-Q1 GND, and then connected to the system ground at one point. Do not connect the various component grounds to each other through the high current ground line. TPS1200-Q1 SLUSEZ3 – DECEMBER 2023 www.ti.com ADVANCE INFORMATION
