TPS2051BQDRQ1 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 voltage |
| 2 | IN | power_in | Supply input voltage, operating range 2.7V to 5.5V |
| 3 | IN | power_in | Supply input voltage, operating range 2.7V to 5.5V |
| 4 | EN | input | Enable input, active high; logic high (≥2V) enables power switch, logic low (≤0.8V) disables |
| 5 | OC | tri_state | Overcurrent open-drain output, active low; asserts at short-circuit current limit (≈1A typical) or thermal shutdown (≈135°C) |
| 6 | OUT | output | Power-switch output, max 500mA continuous current, 105mΩ typical ON-state resistance |
| 7 | OUT | output | Power-switch output, max 500mA continuous current, 105mΩ typical ON-state resistance |
| 8 | OUT | output | Power-switch output, max 500mA continuous current, 105mΩ typical ON-state resistance |
