TPS3703A3250DSER

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

TPS3703A3250DSER 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 VIT+ or falls below the undervoltage threshold VIT-. Connect to VDD to monitor the VDD supply.
2 VDD power_in Supply voltage input; 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: connecting it to VDD or leaving it floating selects one of two fixed reset delays, and an external capacitor to ground programs the delay time.
4 RESET output Active-low open-drain output that goes low when SENSE is above VIT+ or below VIT-; it must be connected to a pull-up resistor tied to the desired pull-up voltage.
5 GND power_in Ground reference pin.
6 MR input Manual reset input: pulling it to logic low (VMR_L) asserts reset, and the reset delay (tD) starts after MR is released; MR can be left floating when not in use.
