# TPS2115APWR

**Texas Instruments** · AC-DC Controllers And Regulators · TSSOP-8

TPS2115APWR from Texas Instruments, in a TSSOP-8. 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 | STAT | output | Open-drain status output; Hi-Z when IN2 switch is ON, pulls low when IN1 switch is ON or OUT is Hi-Z. |
| 2 | D0 | input | TTL/CMOS-compatible control input with 1-μA pull-up; used with D1 for switching selection per Truth Table. |
| 3 | D1 | input | TTL/CMOS-compatible control input with 1-μA pull-up; used with D0 for switching selection per Truth Table. |
| 4 | ILIM | input | Current limit input; resistor RILIM connected to GND sets current limit IL to 500/RILIM for TPS2115A. |
| 5 | GND | power_in | Ground connection. |
| 6 | IN2 | input | Secondary power input at 2.8V to 5.5V; enabled if supply above UVLO threshold and at least one supply exceeds internal VDD UVLO. |
| 7 | OUT | output | Power switch output capable of 1.25A maximum continuous current at nominal operating conditions. |
| 8 | IN1 | input | Primary power input at 2.8V to 5.5V; enabled if supply above UVLO threshold and at least one supply exceeds internal VDD UVLO. |
