TPS2051ADR from Texas Instruments, in a SOIC-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | GND | power_in | Device ground return for the switch and internal control circuitry. Tie to the system 0 V rail. |
| 2 | IN | power_in | Power-switch input voltage (2.7 V to 5.5 V). Pins 2 and 3 are the source of the internal N-channel high-side MOSFET and must be tied together and bypassed close to the device. |
| 3 | IN | power_in | Power-switch input voltage (2.7 V to 5.5 V). Pins 2 and 3 are the source of the internal N-channel high-side MOSFET and must be tied together and bypassed close to the device. |
| 4 | EN | input | Enable input, CMOS/TTL compatible. Logic HIGH turns the power switch on (TPS205xA is active-high). Do not leave floating. |
| 5 | OC | output | Overcurrent flag, open-drain active-low. Asserts low when the switch enters current limit or thermal shutdown. Requires an external pull-up resistor to a logic rail (typ. 10 kΩ to VCC). |
| 6 | OUT | power_out | Power-switch output (drain of the internal N-channel high-side MOSFET). Pins 6, 7 and 8 are the same OUT node and must be tied together; rated 500 mA continuous per channel, 0.9 A typical short-circuit current limit. |
| 7 | OUT | power_out | Power-switch output (drain of the internal N-channel high-side MOSFET). Pins 6, 7 and 8 are the same OUT node and must be tied together; rated 500 mA continuous per channel, 0.9 A typical short-circuit current limit. |
| 8 | OUT | power_out | Power-switch output (drain of the internal N-channel high-side MOSFET). Pins 6, 7 and 8 are the same OUT node and must be tied together; rated 500 mA continuous per channel, 0.9 A typical short-circuit current limit. |
