TPS259571DSGR 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 | output | A capacitor from this pin to GND sets the output turn-on slew rate up to maximum pin voltage of 2.5 V; leave floating for fastest slew rate. |
| 2 | EN/UVLO | input | Active high enable input with adjustable undervoltage lockout threshold (0-6 V range) via resistor divider; must not be left floating. |
| 3 | IN | power_in | Power supply input pin accepting 2.7-18 V input voltage. |
| 4 | IN | power_in | Power supply input pin accepting 2.7-18 V input voltage. |
| 5 | OUT | power_out | Power supply output pin with voltage range 0 to VIN + 0.3 V. |
| 6 | FLT | output | Open-drain fault indicator output that pulls low on fault detection; requires external pull-up resistance and supports maximum sink current of 10 mA. |
| 7 | ILM | bidirectional | Dual-function analog I/O pin where external resistor (487-5000 Ω) sets current limit threshold and pin voltage monitors output load current; must not be left floating. |
| 8 | GND | power_in | Ground connection. |
| 9 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
