TPS259531DSGR 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 | input | Slew rate control input; external capacitor to GND sets output rise time; maximum voltage 2.5 V; open = 38.2 V/ms at 12 V. |
| 2 | EN/UVLO | input | Active-high enable input with programmable undervoltage lockout threshold (1.2 V typical rising threshold) adjustable via external resistor divider; do not leave floating. |
| 3 | IN | power_in | Power supply input; operating range 2.7 to 18 V, absolute maximum 20 V. |
| 4 | IN | power_in | Power supply input; operating range 2.7 to 18 V, absolute maximum 20 V. |
| 5 | OUT | power_out | Power output; voltage range 0 to (VIN + 0.3) V, maximum continuous current 4 A at junction temperature −40 to 125°C. |
| 6 | FLT | tri_state | Open-drain fault indicator output; pulled low on thermal shutdown, overcurrent, or other fault conditions; maximum sink current 10 mA. |
| 7 | ILM | bidirectional | Current limit and load monitoring I/O pin; external resistor to GND (487 to 5000 Ω range) sets maximum output current; pin voltage monitors load current at 276 µA/A typical gain. |
| 8 | GND | power_in | Ground reference pin; must be connected to PCB ground plane. |
| 9 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
