Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | IN | power_in | IN is the source of the internal N-channel MOSFET and the anode of the ideal diode, and the IN pins are protected against reverse inputs of up to -40V. |
| 2 | IN | power_in | IN is the source of the internal N-channel MOSFET and the anode of the ideal diode, and the IN pins are protected against reverse inputs of up to -40V. |
| 3 | IN | power_in | IN is the source of the internal N-channel MOSFET and the anode of the ideal diode, and the IN pins are protected against reverse inputs of up to -40V. |
| 4 | IN | power_in | IN is the source of the internal N-channel MOSFET and the anode of the ideal diode, and the IN pins are protected against reverse inputs of up to -40V. |
| 5 | SHDN | input | SHDN is the shutdown control input: pulling it below 0.6V shuts the part down and pulling it above 2V turns it on, and it can be pulled up to 40V without damage. |
| 6 | NC | unconnected | NC is a no connection pin that is not internally connected. |
| 7 | INK | power_in | INK is the voltage sense and supply voltage pin, which must be connected to IN and has an operating supply range of 4V to 40V. |
| 8 | CS | passive | CS is the gate drive return, through which the fast pull-down current flows during a reverse current event, and it can be connected to IN or left open. |
| 9 | GATE | output | GATE is the gate drive output that pulls high to enhance the N-channel MOSFET when load current creates more than 30mV of drop, and turns the MOSFET off within 300ns on reverse current. |
| 10 | OUTK | input | OUTK is the drain voltage sense pin, which must be connected to OUT to control the MOSFET voltage drop. |
| 11 | VSS | power_in | VSS is the device ground, and all voltages are referenced to VSS unless otherwise specified. |
| 12 | NC | unconnected | NC is a no connection pin that is not internally connected. |
| 13 | IN | power_in | IN is the source of the internal N-channel MOSFET and the anode of the ideal diode, and the IN pins are protected against reverse inputs of up to -40V. |
| 14 | IN | power_in | IN is the source of the internal N-channel MOSFET and the anode of the ideal diode, and the IN pins are protected against reverse inputs of up to -40V. |
| 15 | IN | power_in | IN is the source of the internal N-channel MOSFET and the anode of the ideal diode, and the IN pins are protected against reverse inputs of up to -40V. |
| 16 | IN | power_in | IN is the source of the internal N-channel MOSFET and the anode of the ideal diode, and the IN pins are protected against reverse inputs of up to -40V. |
| 17 | OUT | power_out | The exposed pad is the drain of the internal N-channel MOSFET and the cathode of the ideal diode, and must be soldered for a low resistance contact. |
