# TPS3702AX33DDCR

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

TPS3702AX33DDCR from Texas Instruments, in a TSOT-23-6. 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 | tri_state | Active-low open-drain undervoltage output; goes low when SENSE voltage falls below the internally set undervoltage threshold (VIT-). |
| 2 | GND | power_in | Ground. |
| 3 | SENSE | input | Input for the monitored supply voltage rail; drives UV low when below undervoltage threshold and drives OV low when above overvoltage threshold. |
| 4 | SET | input | Input pin to configure the device's threshold voltages. |
| 5 | VDD | power_in | Supply voltage input pin (2V to 18V); place a 0.1µF ceramic capacitor close to this pin. |
| 6 | OV | tri_state | Active-low open-drain overvoltage output; goes low when SENSE voltage rises above the internally set overvoltage threshold (VIT+). |
