Texas Instruments · Power Distribution Switches · SON-8-EP(3x3)
TPS2042BDRBR 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 connection; reference potential for all pins. |
| 2 | IN | input | Input supply voltage; operating range 2.7V to 5.5V. |
| 3 | EN1 | input | Active-low enable input for OUT1 power switch; logic low activates the switch. |
| 4 | EN2 | input | Active-low enable input for OUT2 power switch; logic low activates the switch. |
| 5 | OC2 | output | Open-drain overcurrent detection output for OUT2; active-low, pulls down on overcurrent condition. |
| 6 | OUT2 | output | Power switch output 2; rated for 500mA continuous current with 70mΩ ON-resistance. |
| 7 | OUT1 | output | Power switch output 1; rated for 500mA continuous current with 70mΩ ON-resistance. |
| 8 | OC1 | output | Open-drain overcurrent detection output for OUT1; active-low, pulls down on overcurrent condition. |
| 9 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
