# TPS3702CX18DDCR

**Texas Instruments** · Supervisor And Reset ICs · TSOT-23-6L

TPS3702CX18DDCR from Texas Instruments, in a TSOT-23-6L. 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 | UV | output | Active-low, open-drain undervoltage output that goes low when SENSE falls below the internal undervoltage threshold (VIT-) and needs a pull-up resistor within the recommended 2.2 kΩ to 10,000 kΩ range. |
| 2 | GND | power_in | Ground reference pin for the device. |
| 3 | SENSE | input | Input for the monitored supply rail, rated 0 V to 6.5 V, which drives UV low below the undervoltage threshold and OV low above the overvoltage threshold. |
| 4 | SET | input | Selects the threshold voltage configuration, with SET pin voltage rated 0 V to 6.5 V, and the mapping is given in the datasheet's table 10-1. |
| 5 | VDD | power_in | Supply voltage input that must be within 2 V to 18 V, with a 0.1 µF ceramic capacitor recommended close to the pin. |
| 6 | OV | output | Active-low, open-drain overvoltage output that goes low when SENSE rises above the internal overvoltage threshold (VIT+) and needs a pull-up resistor within the recommended 2.2 kΩ to 10,000 kΩ range. |
