PIN FUNCTIONS
GATE: Gate Drive for External N-Channel MOSFET. An
internal charge pump provides a 10A pull-up current
to charge the gate of the external N-channel MOSFET. An
additional ramp circuit limits the GATE ramp rate when
turning on to 3V/ms. For slower ramp rates, connect an
external capacitor from GATE to GND. An internal clamp
limits GATE to 6V above the OUT pin voltage. An internal
GATE high comparator controls the PWRGD pin.
GATEP (LTC4360-2): Gate Drive for External P-Channel
MOSFET.GATEPconnectstothegateofanoptionalexternal
P-channel MOSFET to protect against negative voltages
at IN. This pin is internally clamped to 5.8V below VIN. An
internal 2M resistor connects this pin to ground. Connect
to IN if not used.
GND: Device Ground.
IN: Supply Voltage Input. Connect this pin to the input
power supply. This pin has an overvoltage threshold of
5.8V. After an overvoltage event, this pin must fall below
VIN(OV) – VOV to release the overvoltage lockout. Dur-
ing lockout, GATE is held low and the PWRGD pull-down
releases.
ON (LTC4360-1): On Control Input. A logic low at ON
enables the LTC4360-1. A logic high at ON activates a
low current pull-down at the GATE pin and causes the
LTC4360-1 to enter a low current sleep mode. An internal
5A current pulls ON down to ground. Connect to ground
or leave open if unused.
OUT: Output Voltage Sense Input for Gate Clamp. Connect
to the source of the external N-channel MOSFET to sense
the output voltage for GATE to OUT clamp.
PWRGD: Power Good Status. Open-drain output with
internal 500k resistive pull-up to OUT. Pulls low 65ms
after GATE ramps above VGATE(TH).
