# NIS5135MN2TXG

**onsemi** · Resettable Fuses · DFN-10(3x3)

NIS5135MN2TXG from onsemi, in a DFN-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 | SOURCE | power_out | Source of the internal power FET and the output terminal of the fuse, with all five source pins connected in parallel inside the device. |
| 2 | SOURCE | power_out | Source of the internal power FET and the output terminal of the fuse, with all five source pins connected in parallel inside the device. |
| 3 | SOURCE | power_out | Source of the internal power FET and the output terminal of the fuse, with all five source pins connected in parallel inside the device. |
| 4 | SOURCE | power_out | Source of the internal power FET and the output terminal of the fuse, with all five source pins connected in parallel inside the device. |
| 5 | SOURCE | power_out | Source of the internal power FET and the output terminal of the fuse, with all five source pins connected in parallel inside the device. |
| 6 | NC | unconnected | Listed as NC in the pin function table; the datasheet assigns it no function. |
| 7 | ILIMIT | passive | A resistor between this pin and the source pin sets the overload and short circuit current limit levels. |
| 8 | Enable/Fault | bidirectional | Tri-state bidirectional enable/fault pin that disables the output when pulled to ground by an open-drain or open-collector device and goes to an intermediate level (Vin-mid 0.82 V to 1.95 V) during thermal shutdown. |
| 9 | dv/dt | passive | Sets the output voltage turn-on slew rate: an internal capacitor gives a default ramp of about 2 ms, an external ceramic capacitor can lengthen it, and the pin is left open if no extra delay is needed. |
| 10 | GND | power_in | Negative input voltage to the device and the internal reference for the IC. |
| 11 | VCC | power_in | Positive input voltage to the device, rated -0.6 V to 18 V steady-state and -0.6 V to 25 V for 100 ms transients relative to GND; this is the belly pad (flag) connection. |
