TPS3703B4250DSERQ1 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 or falls below the undervoltage threshold, and SENSE should be connected to VDD when monitoring the VDD supply. |
| 2 | VDD | power_in | Supply voltage input pin; good analog design practice is to place a 0.1-µF ceramic capacitor close to this pin. |
| 3 | CT | input | Capacitor time delay pin: connecting CT 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+ (overvoltage) or below VIT- (undervoltage) and must be connected to a pull-up resistor to the desired pull-up voltage. |
| 5 | GND | power_in | Ground reference pin. |
| 6 | MR | input | Manual reset input: pulling it to a logic low (VMR_L) asserts reset, and RESET is released after the reset delay tD expires once MR is deasserted; MR can be left floating when not in use. |
