TIMER (Pin 4): Analog Current Fault Inhibit Timing Input.
Connect a capacitor from TIMER to GND. With the chip
turned off (ON = GND or ON = High) or the internal circuit
breaker tripped (FAULT = GND), the TIMER pin is internally
held at GND. When the chip is turned on, a 22礎 pull-up
current source is connected to TIMER. Current limit faults
will be ignored until the voltage at the TIMER pin rises to
within 0.9V of 12V

.
ON/ON (Pin 5): Digital Input.The LTC1643AL/LTC1643AL-1
have an active low enable, ON, and the LTC1643AH has an
active high enable, ON. When the ON pin is pulled high or

IN
 (Pin 1): 12V Supply Input. It powers all the chips
internal circuitry. A 0.5& switch is connected between
12V
IN
 and 12V
OUT
 with a foldback current limit. An under-
voltage lockout circuit prevents the switches from turning
on while the 12V
IN
 pin voltage is less than 9.5V typically.

  (Pin 2):    12V  Supply  Input.  A  1.2&  switch  is
connected between V
EEIN
  and V
EEOUT
  with a foldback
current limit.
3V
OUT
 (Pin 3): Analog Input. Used to monitor the 3.3V
output supply voltage. The PWRGD signal cannot go low
until the 3V
OUT
 pin exceeds 2.9V typically.
