TPS3703A7125DSERQ1

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

TPS3703A7125DSERQ1 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 pin, and good analog design practice is to place a 0.1-µF ceramic capacitor close to this pin.
3 CT input Capacitor time delay pin that selects one of two fixed reset delays when tied to VDD or left floating, or 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 rises above the overvoltage threshold (VIT+) or falls below the undervoltage threshold (VIT-), and it must be connected to a pull-up resistor terminated to the desired pull-up voltage.
5 GND power_in Ground connection for the device.
6 MR input Manual reset input that asserts a reset when pulled to a logic low (VMR_L), with RESET going high after the reset delay time (tD) expires once MR is deasserted, and it can be left floating when not in use.
