Description
The EiceDRIVER™ gate driver 1EDI3038AS is a high voltage galvanic isolated SiC-MOSFET driver designed for high voltage automotive applications. The device is based on Infineon’s coreless transformer (CT) technology providing 8 kV galvanic insulation between low voltage and high voltage domains. The IC supports up to 1200 V SiC-MOSFETs. The device features a powerful output stage of up to 15 A peak current required for high power switches. A split output stage (TON, TOFF) allows different slew rates for switching on and switching off due to separate gate resistors. The low voltage domain (primary side) supports logic levels of 5 V as well as 3.3 V. At the high voltage domain (secondary side) it can drive the gate of SiC-MOSFETs directly. A short propagation delay of only 60 ns and a minimum pulse width of 150 ns offer high a switching frequency with minimum distortion of the PWM signal. The DESAT protection together with the configurable external soft turn-off feature prevents SiC-MOSFETs destruction in short-circuit events. The integrated active Miller clamping stage up to 10 A allows unipolar supply of the SiC-MOSFET. The device features a DATA interface that provides detailed error diagnosis through a PWM signal. A large panel of integrated safety related features simplifies the design of ASIL D compliant systems. Safety inputs (SI1, SI2) at the primary side control the transition of the system to safe state. Additionally, the device offers a secondary side active short circuit (ASC) pin to trigger safe state also from the secondary side.

4.2 Operating modes description
The device has the following modes which it can operate in:
- Primary_Init mode
- PWM Disable mode
- PWM Enable mode
- ASCP_ON mode Primary_Init mode and start up The device is in Primary_Init mode at start-up if an primary internal supervision or an UVLO1 error occurs. In both cases it will not operate as the primary die is not ready. DATA is pulled to "low" . PWM Disable mode
- In PWM Disable mode with NFL T = "high" and RDY = "high" no error occurred.
- In PWM Disable mode with NFL T or RDY = "low" an error occurred. Mode transition to PWM Enable mode Once in PWM Disable mode the change to PWM Enable mode is done with setting SI1 and SI2 signal to "high" . Changing the state of SI2 back to "low" the device is returning into PWM Disable mode. PWM Enable mode In PWM Enable mode the output gate voltage is following the signal transitions on INP in case there is no STP keep error between INP & INN input signals. ASCP_ON mode Setting SI1 = "low" and SI2= "high" transitions the device state to ASCP_ON mode after a defined delay. During this mode the switching state transition via INP signal is disabled. The output stage is in a stable "high" condition. Changing the state of SI2 to "low" shifts the device back to PWM Disable mode with a defined delay. If an error related to NFL T or RDY occurs, the device is shifted to PWM Disable Mode. A state transition from ASCP_ON mode to PWM Enable mode is prohibited. Error transitions The transition from PWM Enable mode or ASCP_ON mode to PWM Disable mode is done according error events which are based on a NFL T error or a RDY error.
4.3 Error classification
The following errors are classified as NFL T error:
- DESAT event In this case NFL T is pulled to "low" . The following errors are classified as RDY error:
- Primary supervision error
- UVLO1 event
- UVLO2 event
- OVLO2 event
- UVLO3 event
- Sec. Internal Supervision error
- Output stage monitoring error
- Gate monitoring error EiceDRIVER™ gate driver 1EDI3038AS Single channel isolated SiC-MOSFET driver
Datasheet 16 Rev. 1.0 2024-06-20
- STP keep error
- Life sign error In all cases RDY transitions to "low" .

5 Primary Side safety control
The device has two dedicated safety inputs on the primary side. The safety inputs control the output stage reaction in the Safety input states table. Table 8 Safety input states table Operation Mode SI1 SI2 Delay TON/TOFF Exception PWM Disable 0 0 tSI_OFF Low (VEE2) Primary_Init mode PWM Disable 1 0 tASCP_OFF Low (VEE2) Primary_Init mode ASCP_ON Mode 0 1 tASCP_ON High (VCC2) Primary_Init mode or events in 'Single failure events in PWM Enable mode and ASCP_ON mode' PWM Enable 1 1 - PWM Primary_Init mode or events in 'Single failure events in PWM Enable mode and ASCP_ON mode'
- If an error related to NFL T or RDY appeared during state transition including the internal delay of SI1 and SI2, the device follows the predefined emergency turn off sequence. The described PWM signal refers to INP/INN signal on primary side input pins. The safety inputs of the HS and LS driver are cross connected, as follows. In that way, if a primary ASC is triggered, the opposite driver is turning off. Hence a shoot through is avoided.

5.1 Functional description of state transitions
PWM Disable mode to PWM Disable mode The device input triggers to change the operation mode from PWM Disable mode to PWM Disable mode via following state transitions:
- SI2 stays "low" and SI1 = "high" .
- SI2 stays "low" and SI1 = "low" . In PWM Disable mode the PWM signal on INP is disabled. PWM Disable mode to PWM Enable mode The device input triggers to change the operation mode from PWM Disable mode to PWM Enable mode via following state transition:
- SI1 = "low" to "high" and SI2 = "low" to "high" - see further information in the Note and in Tsafety diagram Only during PWM Enable mode the PWM signal on INP is a valid input signal for the output stage. In case INP is "high" before PWM Enable mode is reached after a delay of tsafety + tSIglitch , TOFF stays "low" . TON is activated by next rising edge on INP . PWM Enable mode to PWM Disable mode The device can be triggered from PWM Enable mode to PWM Disable mode via safety inputs with following state transitions:
- SI1 = "low" and SI2 = "low" . After tSI_OFF delay is elapsed, TON switches ''low'' .
- SI1 stays "high" and SI2 = "low" . After tASCP_OFF delay is elapsed, TON switches ''low'' . After internal recognition of the transition via the safety inputs the output stage does not follow the INP signal. In case there is a state transition on INP from "high" to "low" or "low" to "high" during tASCP_OFF or tSI_OFF this transition is disabled. PWM Disable mode to ASCP_ON mode The device can be triggered to change the operation state from PWM Disable mode to ASCP_ON mode via following transition on SI1 and SI2 : SI1 = "low" and SI2 = "high" An additional delay is included into this state transition and is defined in tASCP_ON. In the PWM Disable and ASCP_ON modes all INP state transitions are ignored. ASCP_ON mode to PWM Disable mode The device triggers a state transitions from ASCP_ON mode to PWM Disable mode via following state transitions on SI1 and SI2:
- SI2 = "low" . After tSI_OFF delay is elapsed, TON switches ''low'' .
- SI1 = "high" and SI2 = "low" . After tASCP_OFF delay is elapsed, TON switches ''low'' . Inside PWM Disable mode and ASCP_ON mode the INP input is ignored. During tSI_OFF and tASCP_OFF the output stage is "high" . PWM Enable mode to ASCP_ON mode The device can trigger a state transition from PWM Enable mode to ASCP_ON mode by setting SI1 to "low" . An additional delay is included and defined in tASCP_ON. In case there is a state transition on INP from "high" to "low" or "low" to "high" during tASCP_ON this transition is ignored. During tASCP_ON the last valid INP signal is active on TON/TOFF. EiceDRIVER™ gate driver 1EDI3038AS Single channel isolated SiC-MOSFET driver
Datasheet 19 Rev. 1.0 2024-06-20
Note: A direct state transition from ASCP_ON mode to PWM Enable mode is prohibited. A direct state transition from PWM Disable mode when SI1 stays "high" by switching SI2 = "high" is prohibited, because when the safety inputs are cross connected to the safety inputs of the opposing gate driver inside a halfbridge topology, the opposing gate driver will otherwise remain in the ASCP_ON mode. When the device is powered-up with SI1 = SI2 = "high" and the device is ready it transitions directly from PWM Disable into PWM Enable.

5.2 Functional description of safety related timings
The device can be switched in between the operating modes via valid signal transitions of SI1 & SI2 from "low" to "high" or "high" to "low" . The safety inputs SI1 and SI2 recognize a valid signal transition in case the signal transition is stable for more than tSIglitch. In case the signal is stable for less than tSIglitch the safety transition timer tsafety is not activated and the signal transition is not valid. At the timestamp of a valid transition from "low" to "high" or "high" to "low" on one safety input a timer starts to count. This time is defined as tsafety. In case of an additional valid signal transition on any safety input during tsafety the timer is started again. If there is no additional valid signal transition during tsafety on any safety input the state transition is executed.

In case the signal transition is beyond the defined safety transition timer the device is executing the recognized state transition after tsafety is elapsed. The tSI_OFF delay defines the delay between following state transitions:
- from PWM Enable mode to PWM Disable mode via the safety pin transitions SI1 = "low" and SI2 = "low" .
- from ASCP_ON mode to PWM Disable mode via the safety pin transitions SI1 stays "low" and SI2 = "low" . The tASCP_ON delay defines the delay between following state transitions:
- from PWM Enable mode to ASCP_ON mode via the safety pin transitions SI1 = "low" and SI2 stays "high" .
- from PWM Disable mode to ASCP_ON mode via the safety pin transitions SI1 stays "low" and SI2 = "high" . The tASCP_OFF delay defines the delay between following state transitions:
- from PWM Enable mode to PWM Disable mode via the safety pin transitions SI1 stays "high" and SI2 = "low" .
- from ASCP_ON mode to PWM Disable mode via the safety pin transitions SI1 = "high" and SI2 = "low" . tSItrans is defined as the minimum time the device needs to stay in the dedicated operation mode state. Switching between states in less than tSItrans is prohibited.

6 Clear functionality
6.1 Functional description clear
In case the device recognizes an error reflected on NFL T or RDY the device operation mode switches to PWM Disable mode. An error is sticky. All error bits can be cleared by a valid state transition starting from PWM Disable mode with SI1 = "low" and SI2 = "low":
- to PWM Enable mode by SI1 = "high" and SI2 = "high" .
- to ASCP_ON mode by SI1 = "low" and SI2 = "high" . If the error reflected on RDY or NFL T disappeared and the internal error bits can be cleared, the device switches back to ASCP_ON mode or PWM Enable mode with the dedicated transition of SI1 and SI2. Error The following errors are mapped to an error bit:
- UVLO2
- UVLO3
- OVLO2
- DESAT error
- OSM error
- Gate monitoring error
- STP keep error The life sign error is raised when the life sign was established once and then lost. The life sign error is not part of the DATA readout. DATA readout contains the No life sign established bit. The No life sign established bit reflects the instantaneous status of the life sign. In case of no life sign error is active all active errors remain sticky until a valid clear command. If the error is present during the clear command, the clear command is not executed. The device stays in PWM Disable mode and RDY or NFL T stays "low" . The clear command via safety inputs needs to be executed again. Warning In case a warning occurred and is recognized by the device it is notified via the diagnostic frame. If the warning source is gone the warning bit is self-cleared after it was transmitted via the diagnostic frame once. Warnings do not impact the state of NFL T or RDY. Even with an activated warning bit the device can execute changes inside the operating states via the valid transitions of SI1 and SI2. The following warnings are mapped to a warning bit:
- DESAT BIST warning
- Dead time warning
- SASC activation warning EiceDRIVER™ gate driver 1EDI3038AS Single channel isolated SiC-MOSFET driver

7 Power supply current consumption
7.1 Functional description power supply current consumption
The device is designed to support two different supply configurations, bipolar supply and unipolar supply.
- In case the unipolar topology is used the device is typically supplied with 15 V on VCC2 and 0 V on VEE2.
- In case the bipolar topology is used the device is typically supplied with 15 V on VCC2 and -5 V on VEE2. In any case of the mentioned topologies it is recommended to connect the GATE/CLAMP directly to the gate of the power semiconductor to prevent unintended turn on caused by parasitic capacitances of the power switch.

8 Power supply monitoring
8.1 Functional description power supply monitoring
The time tPS2RDY is defining the time from the detection of an undervoltage or an overvoltage event on any of the monitored voltage rails VCC1 ,VCC2 ,VEE2 until the notification by changing RDY to "low" .
8.1.1 Functional description at VCC1
The device is equipped with an undervoltage lockout on the primary supply of VCC1 in order to ensure the correct behavior of the device. In case the voltage on VCC1 is exceeding VUVLO1,H1 the primary side state changes from power down mode into PWM Disable mode. Note: In all undervoltage conditions SASC signal still works until voltage drops below VASCOFF at VCC2. Primary ASC via SI1 and SI2 is deactivated in case UVLO1 is detected. The detection & reaction time tUVLO1OFF is started by crossing the low threshold of undervoltage functionality VUVLO1L_1 , and stops when TON = VVCC2 - 1.5V. The reaction is taken whether the fault is cleared during tUVLO1OFF or not. In case the voltage on VCC1 drops below VUVLO1L _1 the device changes into Primary INIT mode.

11 Shoot Through Protection (STP)
11.1 Functional description STP
The device has an always active Shoot Through Protection (STP) function to prevent both highside and lowside switches to be activated simultaneously. Exception: If the device is in ASCP_ON mode or in a valid transition to ASCP_ON mode the Shoot Through Protection functionality is disabled and RDY switches to "high" . Setting INN pin to GND1 deactivates the function. Note: In case INP is shorted to INN and both are activated simultaneously, the output stage might be switched to "high" . If one of the drivers is in ON state, the driver’s counterpart PWM input is inhibited, preventing it to turn on.

14 DESAT protection
14.1 Functional description DESAT protection
The device monitors the voltage across the power switch during TON = "high" after the DESAT blanking time tDESATBTx is elapsed. If the corresponding reference level VDESATx is reached, it issues a safe turn-off within tDESAT2SOFTOFF. The device executes a state change into the PWM Disable mode. The output stage is changed into tristate. The desaturation event is signaled by clamping NFL T to "low" within tDESAT2NFL T. DESAT LOGIC GND2 EiceDRIVER™ Vcc2 Threshold Current source enable Clamping enable NFLT generation R DESAT C DESAT D DESAT GND2 Figure 17 Desaturation principal application schematic The DESAT pin has an internal clamping transistor to VDESATL in following cases:
- TON = "low"
- Safe turn off is activated
- Output stage monitoring error is active. The negative transient current describes the robustness of the internal desaturation clamping MOSFET against current spikes entering the device.

14.2 Functional description DESAT BIST
The device has an built in self test to supervise the DESAT functionality. The desaturation built in self test is executed whenever VVCC2 exceeds VUVLO2Hx after an UVLO2 was raised. An artificial DESAT event is generated once, in order to monitor the functionality of the internal current source, the internal threshold comparator and the external connected components. The internal clamping is deactivated for up to tDESAT_BIST_CLAMP or until the internal threshold comparator is triggered. The artificial DESAT event is processed internally for up to tDESAT_BIST. The DESAT BIST result is stored inside the No Desaturation BIST warning bit, which is shown in the DATA diagnostic frame. In case DESAT BIST succeeded without errors the the No Desaturation BIST warning bit is switched to "1" . This bit is latched and cannot be cleared via valid clear signal. In case the internal comparator is not triggered, the DESAT functionality has a malfunction and the No Desaturation BIST warning bit inside the DATA diagnostic frame stays "0" .

15 Soft turn off
15.1 Functional description soft turn off
The soft turn off functionality ensures a safe turn off in case of an emergency to prevent high voltage overshoots on the power semiconductor. The activation of the SOFTOFF pin is described as a safe turn off. The safe turn off functionality is executed when following failures appear in the system and are recognized by the device :
- Desaturation protection
- Gatemonitoring error In case of an error, the safe turn off functionality is activated, TON and TOFF is tri-stated and the power semiconductor safe turn off is done using the SOFTOFF pin. The safe turn off function via SOFTOFF is deactivated if VGATE undershoots VCLAMP .

17 Output stage monitoring
The output stage monitoring function monitors if the measured TON/TOFF signal is following the input control signals within tOSM-CPL.. If a mismatch is detected the device switches TON/TOFF into tri-state in less than tOUTM-TRI and changes to PWM Disable mode. RDY is pulled to "low" within tRDY_OSM. The TON/TOFF can be controlled from:
- The primary side PWM input INP and INN
- The primary side safety inputs SI1 and SI2
- The secondary side SASC input In case the output stage monitoring functionality detects a failure it tri-states the output stage. After tOSM_retry the tri-state of TON/TOFF is released and the device switches the output stage to "low" . In case another output stage monitoring error is detected the tOSM_retry timer starts again.

Note: In a half bridge configuration the switched off power switch tends to dynamically turn on during the turn on phase of the opposite power switch.

22 Fault (NFL T)
22.1 Functional description NFL T
NFL T reports short circuit events. The pin is active "low" . If the device switches into safe turn off of the output stage due to a DESAT event, it goes to PWM Disable mode and signals the event on pin NFL T by changing NFL T to "low" . The tDESAT2NFL T time is defining the time from the detection of a DESAT event until the notification on NFL T . The device keeps the fault signal available unless a clear event takes place.
