**Texas Instruments** · Surge Protection Devices (SPDs) · WSON-6(2x2)

TPS25961DRVR from Texas Instruments, in a WSON-6(2x2). Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | OUT | power_out | Power output for loads up to 2 A continuous current with voltage equal to input minus on-resistance drop. |
| 2 | OVLO | input | Analog input for overvoltage lockout threshold adjustment; connect to GND for fixed 5.98 V threshold or to external resistor divider for custom threshold within 0.5 V to 1.5 V recommended range; do not leave floating. |
| 3 | ILIM | output | Analog output for setting output current limit threshold via external resistor to GND, configurable from 116 mA minimum (open) to 2.36 A (with 25 kΩ resistor). |
| 4 | GND | power_in | System ground connection; must be connected to PCB ground plane. |
| 5 | EN/UVLO | input | Active-high enable input for undervoltage lockout control; recommended voltage range up to 5 V for supplies below 5 V, or divided supply with minimum 350 kΩ pull-up for supplies above 5 V; do not leave floating. |
| 6 | IN | power_in | Power supply input; accepts voltage range from 2.7 V to 19 V nominal (absolute maximum 21 V) with typical quiescent current of 130 μA. |
| 7 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
