TPS2112PWR 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 switch status output that is Hi-Z when IN2 switch is ON, or pulls low when IN1 switch is ON or output is Hi-Z. |
| 2 | EN | input | TTL and CMOS compatible enable input with 1-µA pull-up for control logic selection. |
| 3 | VSNS | input | Voltage sense input that selects IN1 path when greater than 0.8 V with 30-60 mV hysteresis, otherwise selects higher of IN1 and IN2. |
| 4 | ILIM | input | Current limit adjustment pin where external resistor RILIM sets limit to 250/RILIM (TPS2112) or 500/RILIM (TPS2113) amperes. |
| 5 | GND | power_in | Ground return. |
| 6 | IN2 | input | Secondary power input accepting 2.8-5.5 V when supply exceeds UVLO threshold and internal VDD UVLO. |
| 7 | OUT | output | Power switch output providing switched connection to selected input. |
| 8 | IN1 | input | Primary power input accepting 2.8-5.5 V when supply exceeds UVLO threshold and internal VDD UVLO. |
