TPS2042BDRBT from Texas Instruments, in a SON-8-EP(3x3). 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. |
| 2 | IN | power_in | Input voltage for both power switches, recommended operating range 2.7 V to 5.5 V. |
| 3 | EN1 | input | Enable input for IN-OUT1, logic low turns on the power switch (TPS2042B), input range 0 to 5.5 V. |
| 4 | EN2 | input | Enable input for IN-OUT2, logic low turns on the power switch (TPS2042B), input range 0 to 5.5 V. |
| 5 | OC2 | output | Overcurrent open-drain output, active low, for IN-OUT2. |
| 6 | OUT2 | power_out | Power-switch output for IN-OUT2, 500 mA maximum recommended continuous output current. |
| 7 | OUT1 | power_out | Power-switch output for IN-OUT1, 500 mA maximum recommended continuous output current. |
| 8 | OC1 | output | Overcurrent open-drain output, active low, for IN-OUT1. |
| 9 | PowerPAD | passive | Internally connected to GND and used to heat-sink the part to the circuit board traces; must be connected to the GND pin. |
