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 20
μ
A 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
IN
.
ON/ON (Pin 5):
Digital Input.The LTC1643L/LTC1643L-1
have an active low enable, ON, and the LTC1643H has an
active high enable, ON. When the ON pin is pulled high or

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

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