TPS259520DSGR from Texas Instruments, in a WSON-8-EP(2x2). 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 | dVdt | bidirectional | A capacitor from this pin to GND sets the output turn-on slew rate, and leaving the pin floating gives the fastest turn-on slew rate; the dVdt pin voltage is limited to 2.5 V maximum. |
| 2 | EN/UVLO | input | Active-high enable for the TPS259520 (x0 variant), where a resistor divider can set the undervoltage lockout threshold, the pin must not be left floating, and the enable pin voltage is specified 0 V to 6 V (7 V absolute maximum). |
| 3 | IN | power_in | Power input with a recommended input voltage range of 2.7 V to 18 V and an absolute maximum of 20 V. |
| 4 | IN | power_in | Power input with a recommended input voltage range of 2.7 V to 18 V and an absolute maximum of 20 V. |
| 5 | OUT | power_out | Power output of the internal eFuse FET, rated for 4 A continuous output current over a junction temperature of −40 °C to 125 °C. |
| 6 | FLT | output | Open-drain fault indicator that is pulled low when a fault is detected, requires an external pull-up resistor, and is limited to 6 V recommended with 10 mA maximum sink current. |
| 7 | ILM | bidirectional | Dual-function pin where an external resistor from this pin to GND (487 Ω to 5000 Ω) sets the output current limit, the pin voltage can monitor load current, and it must not be left floating. |
| 8 | GND | power_in | Ground reference for the device. |
| 9 | GND | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
