36V System Power Supply with Watchdog Timer for Automotive Applications No. EC-361-231121 OUTLINE R5111x is the system power supply and supervisor IC based on the high- voltage CMOS process technology, and has high accuracy and ultra low supply current voltage. R5111x consists of a voltage regulator (VR), a voltage detector (VD), and a normal / window type of watchdog timer (WDT) in a chip, and can provide three functions of the system power supply, the supply voltage supervisor, and the supervision of system ’s miss operation. Voltage Regulator allows the output current of 300 mA. And, VR has the inrush current protection circuit for rising pulse (Typ.250 mA or less). Voltage Detector outputs a reset signal when a reduction of supply voltage (SENSE / VOUT) is detected, and the reset signal is used as system reset. The detection voltage is internally fixed in an IC. And, the delay time is adjustable with an external capacitor because VD has the built-in release delay circuit (the power-on reset circuit). When the supply voltage is higher than the release output voltage, VD maintains the reset state during the delay time. The output type of RESETB and DOUT are Nch open-drain. In addition, R5111xxx2C and R5111xxx2D (Detector with SENSE pin) have a manual reset (MR) pin. Watchdog Timer detects the microprocessor output pulse. In addition to the normal type of WDT (R5111Sxx1A / R5111xxx2C) that outputs a reset signal when the detected pulse period is longer than normal, R5111 x supports the window type of WDT (R5111Sxx1B / R5111xxx2D) that outputs a reset signal when the detected pulse period is shorter or longer. RESETB outputs the reset signal when using R5111Sxx1A / R5111Sxx1B, and the WDO pin outputs “L” as the reset signal when using R5111xxx2C / R5111xxx2D. The output type of WDO is Nch open- drain. In addition, R5111xxx2C and R5111xxx2D have an inhibiting (INH) pin to stop the watchdog timer’s monitoring function. The time out period of Watchdog Timer is also adjustable with an external capacitor. R5111x supports the packages of HSOP-8E, HSOP-18 and HQFN0808-28.

After that, the TW pin voltage (VTW) repeats charge and discharge. As a result, a sawtooth wave is generated. The WDT has three states: Ignoring, Reset, and Monitoring. In each state, the TW pin is charged from 0 V or TWFREFL (Typ.0.08 V). (2) After the WDT starts, the WDT is in an ignoring state until VTW is charged up to TWVREFH (Typ.2 V). So, a pulse to the SCK pin is ignored during the ignoring state. (3) When charging VTW up to TWVREFH has completed, the TW pin starts discharging and the WDT goes into a monitoring state. (4) When a pulse is not sent to the SCK pin before VTW reaches TWVREFH during the monitoring state, the TW pin starts discharging and the WDT goes into a reset state. During the reset state, VRESETB becomes “L”. (5) When VTW is charged up to TWVREFH during the reset state, the TW pin starts discharging and the WDT goes into the ignoring state. (6) When a pulse is sent to the SCK pin before VTW reaches TWVREFH during the monitoring state, the TW pin start discharging and the WDT goes into the next open window state.

After that, th e TW pin voltage (V TW) repeats charge and discharge. As a result, a sawtooth wave is generated. The WDT has four states: Ignoring, Reset, Open Window, and Closed Window. In each state, the TW pin is charged from 0 V or TWVREFL (Typ.0.08 V). (2) After WDT starts, the WDT is in an ignoring state until VTW is charged up to TWVREFH (Typ.2 V). So, a pulse to the SCK pin is ignored during the ignoring state. (3) When VTW is charged up to TWVREF H during the ignoring state, the TW pin starts discharging and the WDT goes into an open window state.

After that, the TW pin voltage (VTW) repeats charge and discharge. As a result, a sawtooth wave is generated. The WDT has three states: Ignoring, Reset, and Monitoring. In each state, the TW pin is charged from 0 V or TWVREFL (Typ.0.08V). (2) After the WDT starts, the WDT is in an ignoring state until VTW is charged up to TWVREFH.

RESETB pin ( R5111Sxx1A/R5111Sxx1B) or DOUT pin (R5111xxx2C/R5111xxx2D) maintains the released output until VCD reaches the threshold voltage of the release output delay pin (V TCD). And when VCD is over VTCD, RESETB pin or DOUT pin is inverted from “L” to “H”. That is, the charged external capacitor starts discharging. When the operating voltage lower than the detector threshold is applied to VDD pin, the detect output delay time, which is the time until the output voltage is inverted from “H” to “L”, remains constant independent of the external capacitor. -VDET+2.0 V 1.5 V VOUT / SENSE GND 5.0 V 2.5 V GND RESETB / DOUT tdelay tPHL Released Output Delay Time Released Output Delay Time (tdelay) indicates the time between the instance when VOUT pin (R5111Sxx1A / R5111Sxx1B) or SENSE pin ( R5111xxx2C / R5111 xxx2D) shifts from “1.5 V” to “−VDET + 2 .0 V” by the application of a pulse voltage and the instance when the output voltage reaches 2.5 V after pulled up RESETB pin (R5111Sxx1A / R5111Sxx1B) or DOUT pin (R5111xxx2C/ R5111xxx2D) to 5.0 V with a resistor of 100 kΩ.

No. EC-361-231121 Inrush Current Prevention at Rising Characteristics R5111x has the inrush current preventing circuit to control the inrush current within about 250 mA limited. This circuit works during the rising periods. Therefore, the load current must be increased after rising up the output voltage (at typ.100 µ s after being out of the inrush current limited condition) by the sequence control. When the load current is increased during the rising periods, the inrush current must be controlled within 150 mA.

No. EC-361-231121 Standby Function When CE turns to low, the R5111x goes into the standby mode. During this mode, the voltage regulator (VR) stops the output, the watchdog timer (WDT) stops the pulse monitoring, and the voltage detector (VD) stops the voltage monitoring. Even if VIN < 3.5 V (Minimum Operating Voltage VMOV), VR stops the output, WDT stops the pulse monitoring, and VD stops the voltage monitoring. When CE = low or VIN < 3.5 V (Minimum Operating Voltage), the output of WDT and VD become as follows regardless of SENSE voltage. R5111Sxx1A/ R5111Sxx1B: The RESETB output is fixed to “L”. R5111xxx2C/ R5111xxx2D: The DOUT is fixed to “L”, and WDO output is fixed to the pull-up voltage. When V IN is under 1.52 V, values of RESETB output (R5111Sxx1A/ R5111Sxx1B) and D OUT output (R5111xxx2C/ R5111xxx2D) become indefinite, 0.1 V or more (pull-up voltage 5 V, pull-up resistance 100 kΩ). Voltage Setting (R5111Sxx1A / R5111Sxx1B) VD detects the drop of the VR output voltage (V OUT). When the VD release voltage (+VDET) is set to a voltage above the VR output voltage, the reset signal of VD is not released even if VD monitors the VR output voltage returns to the normal value after detecting the drop of VR. To prevent this issue, the following condition is required between VOUT and +VDET. (VR Set Output Voltage) x 0.985 – 30 mV > (VD Set Detector Threshold) x 1.018 x 1.030 When using a device with the above conditions of V OUT and +VDET, careful consideration must be given to the system operation before use.

No. EC-361-231121 Manual Reset (MR) Function (R5111xxx2C, R5111xxx2D) Setting the MR pin to “L” forcefully sets DOUT to “L”. The maximum value of the delay time (tMR), which is until DOUT outputs “L”, is 1 µs as an index of the performance. The MR pin is pulled- up by an internal resistor (Typ.110 kΩ). Current is passed to the MR pin when the voltage of MR > VDD. But, this current has no effect to the operation because the current is limited with a pull-up resistor. When setting the MR pin from “L” to “H”, DOUT is changed from “L” to “H” after the released output delay time and the WDT starts from the ignoring state. When the MR pin is “L”, the WDO pin outputs “H”. SENSE Function (R5111xxx2C, R5111xxx2D) The internal voltage detector monitors the input voltage to the SENSE pin. To measure the proper detector threshold, setting of VIN ≥ 3.5 V is required. Inhibition (INH) Function (R5111xxx2C, R5111xxx2D) Setting the INH pin to “L” stops the WDT pulse monitoring function and the WDO pin is fixed to “H” . The INH pin is pulled up with an internal resistor (Typ.110 kΩ).

No. EC-361-231121 External Components Symbol Description C1 (CIN) 0.1 µF, Ceramic Capacitor C2 (COUT) 0.1 µF, Ceramic Capacitor CTW A capacitor corresponding to time setting for Watchdog Timer is required. Refer to “Time Setting for WDT” in Operation Description for details. CD A capacitor corresponding to setting for Release Output Delay Time is required. Refer to “Delay Operation and Release Output Delay Time (tdelay)” in Operation Description for details. R1 A resistor is required to set with consideration of the output current and the leakage current. Refer to “Electrical Characteristic” for details. TECHNICAL NOTES Phase Compensation In the ICs, phase compensation is made for securing stable operation even if the load current is varied. For this purpose, use a capacitor C2 with 0.1 µF or more. If a tantalum capacitor is used, and its ESR (Equivalent Series Resistance) of C2 is large, the loop oscillation may result. Because of this, select C2 carefully considering its frequency characteristics. PCB Layout Make VDD and GND lines sufficient. If their impedance is too high, noise pickup or unstable operation may result. Connect 0.1 µF or more of the capacitor C1 between the VDD and GND, and as close as possible to the pins. In addition, connect the capacitor C2 between VOUT and GND, and as close as possible to the pins.
