Pinout

Pin	Name	Type	Function
1	VIN	power_in	Power supply input with a maximum protection range of -40V to 100V and an operating range of 2.5V to 60V; it can be hot swapped and has a 2.2V UVLO.
2	UV	input	Undervoltage comparator input with a 0.5V falling threshold and 25mV of hysteresis, set by an external resistive divider; if unused and VIN is below 80V, connect it to VIN through a 510k resistor.
3	OV	input	Overvoltage comparator input with a 0.5V rising threshold and 25mV of hysteresis, set by an external resistive divider; connect to GND if unused.
4	RETRY	input	Retry or latch-off selection input that latches off the MOSFETs after a forward overcurrent fault when tied to ground, or sets a 5.5ms/nF retry delay when connected to a capacitor; absolute maximum rating is -0.3V to 5V, and it should be left unconnected if unused.
5	GND	power_in	Device ground.
6	SHDN	input	Shutdown control input where high enables the gate charge pump and low pulls GATE down with a 90µA sink and places the part in 5µA low-current mode; SHDN must be kept below 80V if VIN goes above 80V.
7	FAULT	output	High-voltage open-drain fault indication output, pulled low on a voltage or current fault, when SHDN is low, or when VIN is below VIN(UVLO), and requiring a pull-up resistor; leave unconnected if unused.
8	VOUT	input	Output voltage sense input used as the gate charge pump reference and by the reverse current fault comparators, which require VOUT to rise above its 2.2V UVLO; place at least 1µF from VOUT to GND and connect a current sense resistor between VOUT and SENSE.
9	SENSE	input	Overcurrent sense input that detects forward faults at 50mV and reverse faults at -50mV (LTC4368-1) or -3mV (LTC4368-2) across the sense resistor between SENSE and VOUT; connect to VOUT if unused.
10	GATE	output	Gate drive output for external N-channel MOSFETs with a 35µA internal pull-up and up to 13.1V of enhancement, pulled just below the lower of VIN or VOUT when off.
