**Texas Instruments** · Power Distribution Switches · SOP-16

TPS2058AD from Texas Instruments, in a SOP-16. 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 | GNDA | power_in | Ground for the IN1 power switch and its circuitry. |
| 2 | IN1 | power_in | Input voltage for the IN1 power switches (OUT1 and OUT2); the device operates from 2.7 V to 5.5 V. |
| 3 | EN1 | input | Active-high enable input; a logic high turns on the IN1-OUT1 power switch. |
| 4 | EN2 | input | Active-high enable input; a logic high turns on the IN1-OUT2 power switch. |
| 5 | GNDB | power_in | Ground for the IN2 power switch and its circuitry. |
| 6 | IN2 | power_in | Input voltage for the IN2 power switches (OUT3 and OUT4); the device operates from 2.7 V to 5.5 V. |
| 7 | EN3 | input | Active-high enable input; a logic high turns on the IN2-OUT3 power switch. |
| 8 | EN4 | input | Active-high enable input; a logic high turns on the IN2-OUT4 power switch. |
| 9 | OC4 | output | Open-drain overcurrent output, active low, for the IN2-OUT4 switch; asserted on overcurrent or over temperature. |
| 10 | OUT4 | power_out | Power-switch output for the IN2-OUT4 channel, current-limited at 0.5 A. |
| 11 | OUT3 | power_out | Power-switch output for the IN2-OUT3 channel, current-limited at 0.5 A. |
| 12 | OC3 | output | Open-drain overcurrent output, active low, for the IN2-OUT3 switch; asserted on overcurrent or over temperature. |
| 13 | OC2 | output | Open-drain overcurrent output, active low, for the IN1-OUT2 switch; asserted on overcurrent or over temperature. |
| 14 | OUT2 | power_out | Power-switch output for the IN1-OUT2 channel, current-limited at 0.5 A. |
| 15 | OUT1 | power_out | Power-switch output for the IN1-OUT1 channel, current-limited at 0.5 A. |
| 16 | OC1 | output | Open-drain overcurrent output, active low, for the IN1-OUT1 switch; asserted on overcurrent or over temperature. |
