TPS3703A5120DSER

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

TPS3703A5120DSER 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 voltage rail; RESET is driven low when SENSE rises above the overvoltage threshold or falls below the undervoltage threshold, and it should be connected to VDD when monitoring the VDD supply.
2 VDD power_in Supply voltage input with a recommended operating range of 1.7 V to 5.5 V, and a 0.1-µF ceramic capacitor should be placed close to this pin.
3 CT input Capacitor time delay pin that selects one of two fixed reset delays when connected to VDD or left floating, or sets a programmed delay when an external capacitor is connected to ground; with CT tied to VDD a 10 kΩ pull-up resistor is recommended.
4 RESET output Active-low open-drain output that goes low when SENSE is above VIT+(OV) or below VIT-(UV), must be connected to a pull-up resistor to the desired pull-up voltage, and is rated for VRESET of -0.3 V to 6 V with output current of 0.3 mA to 10 mA recommended.
5 GND power_in Ground reference pin for the device.
6 MR input Manual reset input that asserts RESET when pulled to a logic low (VMR_L), may be left floating when not in use because it is internally pulled up to VDD, and is rated for VMR of 0 V to 5.5 V.
