TPS259521DSGR 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 | A capacitor from this pin to GND sets the output turn on slew rate; leave this pin floating for the fastest turn on slew rate. |
| 2 | EN/UVLO | input | Active high enable for the TPS259521; a resistor divider can be used to adjust the undervoltage lockout threshold and must not be left floating. |
| 3 | IN | power_in | Power input; input voltage range 2.7 V to 18 V. |
| 4 | IN | power_in | Power input; input voltage range 2.7 V to 18 V. |
| 5 | OUT | power_out | Power output; output voltage 0 to VIN + 0.3 V. |
| 6 | FLT | tri_state | Fault event indicator pulled low when a fault is detected; open-drain output requiring external pull-up resistance. |
| 7 | ILM | bidirectional | Current limit and monitor pin; an external resistor from this pin to GND sets the output current limit (487 Ω to 5000 Ω) and pin voltage monitors output load current; must not be left floating. |
| 8 | GND | power_in | Ground reference connection. |
| 9 | GND | power_in | Exposed thermal pad for heat dissipation and must be connected to GND. |
