TPS3703A5290DSERQ1

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

TPS3703A5290DSERQ1 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+(OV) or falls below the undervoltage threshold VIT-(UV), and it should be tied to VDD to monitor 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.
3 CT input Capacitor time delay pin that selects a fixed delay when tied to VDD (through a 10 kΩ pull-up, recommended) or left floating, or programs the delay when an external capacitor is connected to ground.
4 RESET output Active-low open-drain output that goes low when SENSE is above VIT+(OV) or below VIT-(UV), and requires a pull-up resistor to a desired voltage with an output current of 0.3 mA to 10 mA recommended (absolute maximum ±40 mA).
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); it may be left floating or connected to VDD because it is internally pulled up, and its voltage is rated 0 V to 5.5 V.
