TPS259541DSGR from Texas Instruments, in a WSON-8-EP(2x2). 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 | dVdt | bidirectional | Capacitor connection to GND sets output turn-on slew rate; leave floating for fastest turn-on. |
| 2 | EN/UVLO | input | Active high enable input; resistor divider adjusts undervoltage lockout threshold. |
| 3 | IN | power_in | Power supply input terminal (2.7V to 18V nominal). |
| 4 | IN | power_in | Power supply input terminal (2.7V to 18V nominal). |
| 5 | OUT | power_out | Power output terminal with integrated FET switching input supply to load. |
| 6 | FLT | output | Fault event indicator, open-drain output pulled low when thermal shutdown, overcurrent limiting, or short circuit is detected. |
| 7 | ILM | bidirectional | Dual-function pin for current limiting and monitoring; external resistor to GND sets output current limit threshold; pin voltage monitors output load current. |
| 8 | GND | power_in | Ground reference terminal. |
| 9 | GND | power_in | Exposed thermal pad for heat dissipation and ground connection; must be soldered to PCB ground plane. |
