TIMER (Pin 1): Timer Input Pin. An external capacitor
C
µF circuit breaker delay. The GATE pin turns off whenever
the TIMER pin is pulled beyond the COMP2 threshold,
such as for overvoltage detection with an external zener.
GND (Pin 2): Ground Pin.
ON (Pin 3): ON Input Pin. The ON pin comparator has a
low-to-high threshold of 1.3V with 80mV hysteresis and a
glitch filter. When the ON pin is low, the LTC4210 is reset.
When the ON pin goes high, the GATE turns on after the
initial timing cycle.
GATE (Pin 4): GATE Output Pin. This pin is the high side
gate drive of an external N-channel MOSFET. An internal
charge pump provides a 10µA pull-up current with Zener
clamps to V

(EA) controls the external MOSFET to maintain a constant
load current. An external R-C compensation network
should be connected to this pin for current limit loop
stability.
SENSE (Pin 5): Current Limit Sense Input Pin. A sense
resistor between the V
