TPS3703A4085DSERQ1 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 pin is driven low when SENSE voltage exceeds overvoltage threshold (VIT+) or falls below undervoltage threshold (VIT-). |
| 2 | VDD | power_in | Supply voltage input pin for device operation (1.7 V to 5.5 V); place 0.1-μF ceramic capacitor close to this pin for proper analog design practice. |
| 3 | CT | input | Capacitor time delay pin; offers two fixed time delays by connecting to VDD or leaving floating; external capacitor to ground programs the reset time delay. |
| 4 | RESET | tri_state | Active-low open-drain output; driven low when SENSE voltage exceeds VIT+ or falls below VIT-; requires pull-up resistor to desired pull-up voltage. |
| 5 | GND | power_in | Ground connection. |
| 6 | MR | input | Manual reset input; pull this pin to logic low to assert reset signal; internally pulled up to VDD and can be left floating when not in use. |
