TPS3703A4180DSERQ1

Texas Instruments · Supervisor And Reset ICs · WSON-6(1.5x1.5)

TPS3703A4180DSERQ1 from Texas Instruments, in a WSON-6(1.5x1.5). Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 SENSE input Input for the monitored supply rail; RESET is driven low when SENSE rises above the overvoltage threshold or falls below the undervoltage threshold, and the recommended SENSE input voltage is 0 V to 5.5 V (connect to VDD when monitoring the VDD supply).
2 VDD power_in Supply voltage input with a recommended range of 1.7 V to 5.5 V, and a 0.1-µF ceramic capacitor should be placed close to this pin for good analog design practice.
3 CT input Capacitor time delay pin that selects one of two fixed delays by connecting it to VDD (with a 10 kΩ pull-up recommended) or leaving it floating, and sets a programmable delay when an external capacitor is connected to ground.
4 RESET output Active-low open-drain output that goes low when SENSE is outside the overvoltage or undervoltage thresholds, and requires a pull-up resistor to the desired voltage with recommended output current of 0.3 mA to 10 mA.
5 GND power_in Ground reference pin for the device.
6 MR input Manual reset input where pulling it to a logic low asserts RESET, its recommended voltage range is 0 V to 5.5 V, and it can be left floating or connected to VDD because it is internally pulled up to VDD.
