TPS259530DSGT 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 the pin should be left floating for the fastest turn-on slew rate. |
| 2 | EN/UVLO | input | Active high enable for the TPS259530 (x0 variant), where a resistor divider can set the undervoltage lockout threshold and the pin must not be left floating. |
| 3 | IN | power_in | Power input for the eFuse, specified at 2.7 V to 18 V with 20 V absolute maximum. |
| 4 | IN | power_in | Power input for the eFuse, specified at 2.7 V to 18 V with 20 V absolute maximum. |
| 5 | OUT | power_out | Power output of the eFuse, with continuous output current up to 4 A over the junction range of -40 to 125 °C. |
| 6 | FLT | output | Open-drain fault indicator that is pulled low when a fault is detected and requires an external pull-up resistor. |
| 7 | ILM | bidirectional | Dual-function pin where an external resistor to GND sets the output current limit (RILM of 487 Ω to 5000 Ω) and the pin voltage monitors load current; it must not be left floating. |
| 8 | GND | power_in | Ground reference pin for the device. |
| 9 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
