TPS3703A5500DSER

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

TPS3703A5500DSER 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, specified from 1.7 V to 5.5 V, with a 0.1-µF ceramic capacitor recommended close to this pin.
3 CT input Capacitor time delay pin that selects one of two fixed delays when tied to VDD or left floating, or sets a programmed delay when an external capacitor is connected to ground; a pull-up resistor (10 kΩ recommended) is required when CT is connected to VDD.
4 RESET output Active-low open-drain output that goes low when SENSE is above VIT+(OV) or below VIT-(UV), and must be connected to a pull-up resistor to the desired pull-up voltage (absolute maximum 6 V).
5 GND power_in Ground reference pin.
6 MR input Manual reset input that asserts RESET when pulled to a logic low (VMR_L); the output returns high after the reset delay tD expires once MR is released, and MR can be left floating when unused because it is internally pulled up to VDD.
