TPS2557QDRBRQ1 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; connect externally to PowerPAD. |
| 2 | IN | power_in | Input voltage; connect a 0.1 μF or greater ceramic capacitor from IN to GND as close to the IC as possible. |
| 3 | IN | power_in | Input voltage; connect a 0.1 μF or greater ceramic capacitor from IN to GND as close to the IC as possible. |
| 4 | EN | input | Enable input, logic high turns on power switch. |
| 5 | ILIM | output | External resistor used to set current-limit threshold; recommended 20 kΩ ≤ R(ILIM) ≤ 187 kΩ. |
| 6 | OUT | power_out | Power-switch output. |
| 7 | OUT | power_out | Power-switch output. |
| 8 | FAULT | tri_state | Active-low open-drain output, asserted during overcurrent or overtemperature conditions. |
| 9 | Thermal Pad | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
