NIS5420MT6TXG from onsemi, in a WDFN-10(3x3). 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 | GND | power_in | Negative input voltage to the device, used as the internal reference for the IC. |
| 2 | dv/dt | passive | Controls the output voltage slew rate at turn on with a 2 ms internal ramp that external capacitance can lengthen, and should be left open if no extra delay is required. |
| 3 | Enable/Fault | bidirectional | Tri-state bidirectional pin that shuts the eFuse down when pulled to ground and indicates thermal shutdown at about 1.4 V, with about 3 V meaning normal operation; do not actively drive it or connect a capacitor to it. |
| 4 | ILimit | passive | A resistor between this pin and the source pin sets the overload and short circuit current limit levels. |
| 5 | ISENSE | output | Load current monitor output for the NIS5420MT6 that allows real-time load current monitoring, with RSENSE connected to GND. |
| 6 | Source | power_out | Source of the internal power FET and the output terminal of the fuse. |
| 7 | Source | power_out | Source of the internal power FET and the output terminal of the fuse. |
| 8 | Source | power_out | Source of the internal power FET and the output terminal of the fuse. |
| 9 | Source | power_out | Source of the internal power FET and the output terminal of the fuse. |
| 10 | Source | power_out | Source of the internal power FET and the output terminal of the fuse. |
| 11 | VCC | power_in | Positive input voltage to the device, with steady-state VCC to GND rated from -0.6 V to 18 V. |
