3.3V
IN
(Pin 17):
3.3V Supply Sense Input. An undervolt-
age lockout circuit prevents the switches from turning on
when the voltage at the 3.3V
IN
pin is less than 2.5V. If no
3.3V input supply is available, short the 3.3V
IN
pin to the
5V
IN
pin.
3.3V
OUT
(Pin 18):
Analog Input Used to Monitor the 3.3V
Output Supply Voltage. The PWRGD pin cannot pull low
until the 3.3V
OUT
pin voltage exceeds 2.9V. If no 3.3V input
supply is available, tie the 3.3V
OUT
pin to the 5V
OUT
pin. A
200
active pull-down discharges 3.3V
OUT
to ground
when the power switches are turned off.
PIU
V
EEOUT
(Pin 19):
-12V Supply Output. A 1
switch is
connected between V
EEIN
and V
EEOUT
. V
EEOUT
must be less
than –11.1V before the PWRGD pin pulls low. The V
EEOUT
power good comparator is disabled for the LTC4244-1. A
390
active pull-up discharges V
EEOUT
to ground when
the power switches are turned off.
12V
OUT
(Pin 20):
12V Supply Output. A 0.5
switch is
connected between 12V
IN
and 12V
OUT
. 12V
OUT
must
exceed 11.1V before the PWRGD pin can pull low. A 440
active pull-down discharges 12V
OUT
to ground when the
power switches are turned off.
