TPS2042D from Texas Instruments, in a SOIC-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 | GND | power_in | Ground reference for the device. |
| 2 | IN | power_in | Input voltage to the power switches, with an operating range of 2.7 V to 5.5 V. |
| 3 | EN1 | input | Enable input for power switch IN-OUT1; a logic low turns the switch on, and the input is compatible with both TTL and CMOS logic levels. |
| 4 | EN2 | input | Enable input for power switch IN-OUT2; a logic low turns the switch on, and the input is compatible with both TTL and CMOS logic levels. |
| 5 | OC2 | output | Open-drain overcurrent output for power switch IN-OUT2, asserted active low on overcurrent or overtemperature. |
| 6 | OUT2 | power_out | Power-switch output for channel 2, rated for a minimum of 500 mA continuous with a maximum on-state resistance of 135 mΩ at VIN = 5 V. |
| 7 | OUT1 | power_out | Power-switch output for channel 1, rated for a minimum of 500 mA continuous with a maximum on-state resistance of 135 mΩ at VIN = 5 V. |
| 8 | OC1 | output | Open-drain overcurrent output for power switch IN-OUT1, asserted active low on overcurrent or overtemperature. |
