TIMER (Pin 1): Timer Input Pin. An external capacitor
C
TIMER
 sets a 272.9ms/礔 initial timing delay and a 21.7ms/
礔 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 10礎(chǔ) pull-up current with Zener
clamps to V
CC
 and ground. In overload, the error amplifier
(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
CC
 and SENSE pins sets the analog
current limit. In overload, the EA controls the external
MOSFET gate to maintain the SENSE pin voltage at 50mV
below V
CC
. When the EA is maintaining current limit, the
TIMER circuit breaker mode is activated. The current limit
loop/circuit breaker mode can be disabled by connecting
the SENSE pin to the V
CC
 pin.
V
CC
 (Pin 6): Positive Supply Input Pin. The operating
supply voltage range is between 2.7V to 16.5V. An under-
voltage lockout (UVLO) circuit with a glitch filter resets the
LTC4210 when a low supply voltage is detected.
