# TPS2113APWR

**Texas Instruments** · Power Distribution Switches · TSSOP-8

TPS2113APWR 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 | tri_state | Open-drain status output pulls low when IN1 switch is enabled or output is high-impedance; high-impedance when IN2 switch is enabled. |
| 2 | EN | input | TTL/CMOS-compatible enable input with internal pull-up; logic 0 enables auto-switching mode, logic 1 disables device per Truth Table. |
| 3 | VSNS | input | Voltage sense input with 0.8 V threshold; routes output to IN1 when above threshold, otherwise routes to higher of IN1 and IN2. |
| 4 | ILIM | input | Current limit adjust input; external resistor RILIM to GND sets limit to 250/RILIM amperes (TPS2112A) or 500/RILIM amperes (TPS2113A). |
| 5 | GND | power_in | Power ground and signal reference. |
| 6 | IN2 | power_in | Secondary power supply input rated 2.8 V to 5.5 V; selectable only when supply exceeds UVLO threshold and internal VDD UVLO threshold is exceeded. |
| 7 | OUT | power_out | Power multiplexer output; connects to IN1 or IN2 based on EN control and VSNS voltage sensing logic. |
| 8 | IN1 | power_in | Primary power supply input rated 2.8 V to 5.5 V; selectable only when supply exceeds UVLO threshold and internal VDD UVLO threshold is exceeded. |
