PIN FUNCTIONS   (8-Lead Package/10-Lead Package)
RESET (Pin 1/Pin 1): An open-drain output that pulls to 
GND if the voltage at the FB pin (Pin 5/Pin 6) falls below
the FB pin threshold (1.236V). During the start-up cycle,
the RESET pin goes high impedance at the end of the
second timing cycle after the FB pin goes above the FB
threshold. This pin requires an external pull-up resistor
to V
CC
. If an undervoltage lockout condition occurs, the
RESET pin pulls low independently of the FB pin to prevent
false glitches.
ON (Pin 2/Pin 2): An active high signal used to enable or 
disable LTC4211 operation. COMP1s high-to-low thresh-
old is set at 1.236V and its hysteresis is set at 80mV. If a
logic high signal is applied to the ON pin (V
ON
 > 1.316V),
the first timing cycle begins if an overvoltage condition
does not exist on the GATE pin (Pin 6/Pin 7). If a logic
low signal is applied to the ON pin (V
ON
 < 1.236V), the
GATE pin is pulled low by an internal 200糀 current sink.
The ON pin can also be used to reset the electronic circuit
breaker. If the ON pin is cycled low and then high following
a circuit breaker trip, the internal circuit breaker is reset,
and the LTC4211 begins a new start-up cycle.
TIMER (Pin 3/Pin 4): A capacitor connected from this pin 
to GND sets the LTC4211s system timing. The LTC4211s
initial and second start-up timing cycles and its internal
power good delay time are defined by this capacitor.
GND (Pin 4/Pin 5): Device Ground Connection. Connect 
this pin to the systems analog ground plane.
FB (Pin 5/Pin 6): The FB (Feedback) pin is an input to the 
COMP2 comparator and monitors the output supply voltage
through an external resistor divider. If V
FB
 < 1.236V, the
RESET pin pulls low. An internal glitch filter at COMP2s
output helps prevent negative voltage transients from
triggering a reset condition. If V
FB
 > 1.239V, the RESET
pin goes high at the end of the second timing cycle.
GATE (Pin 6/Pin 7): The output signal at this pin is the 
high side gate drive for the external N-channel FET pass
transistor.
As shown in the Block Diagram, an internal charge pump
supplies a 10糀 gate current and sufficient gate volt-
age drive to the external FET for supply voltages from
2.5V to 16.5V. The internal charge-pump and zener
