LTC1727/LTC1728
(LTC1727/LTC1728)
PIU
V
CC3
(Pin 1/Pin 5):
3.3V Sense Input and Power
Supply Pin. (3V Sense Input and Power Supply Pin for
LTC1728-1.8.) This pin provides power to the part
when the voltage on V
CC3
is greater than the voltage on
V
CC5
/V
CC25
/V
CC18
. Bypass to ground with a
≥
0.1
μ
F
ceramic capacitor.
V
CC5
(Pin 2/Pin 4):
5V Sense Input and Power Supply
Pin. This pin is used on the LTC1727-5/LTC1728-5 to
provide power to the part when the voltage on V
CC5
is
greater than the voltage on V
CC3
. Bypass to ground with
a
≥
0.1
μ
F ceramic capacitor.
V
CC25
(Pin 2/Pin 4):
2.5V Sense Input and Power Supply
Pin. This pin is used on the LTC1727-2.5/LTC1728-2.5 to
provide power to the part when the voltage on V
CC25
is
greater than the voltage on V
CC3
. Bypass to ground with
a
≥
0.1
μ
F ceramic capacitor.
V
CC18
(Pin 2/Pin 4):
1.8V Sense Input and Power Supply
Pin. This pin is used on the LTC1728-1.8 to provide
power to the part when the voltage on V
CC18
is greater
than the voltage on V
CC3
. Bypass to ground with a
≥
0.1
μ
F
ceramic capacitor.
V
CCA
(Pin 3/Pin 3):
1V Sense, High Impedance Input. If
unused, it can be tied to either V
CC3
or V
CC5
/V
CC25
/V
CC18
.
GND (Pin 4/Pin 2):
Ground.
COMPA (Pin 5):
V
CCA
Comparator Output for the LTC1727.
Active high, open-drain logic output with weak pull-up to
V
CC3
. Asserted when V
CCA
is above V
RTA
. Deasserted
when V
CCA
is below V
RTA
or if both the V
CC3
and V
CC5
supply pins are too low to power the internal bandgap
reference (typically <2.0V). Can be pulled greater than
V
CC3
using an external pull-up.
RST (Pin 6/Pin 1):
Reset Logic Output. Active low, open-
drain logic output with weak pull-up to V
CC3
. Can be pulled
up greater than V
CC3
when interfacing to 5V logic. As-
serted when one or all of the supplies are below trip thresh-
olds and held for 200ms after all supplies become valid.
COMP5 (Pin 7):
V
CC5
Comparator Output for the
LTC1727-5. Active high, open-drain logic output with
weak pull-up to V
CC3
. Asserted when V
CC5
is above V
RT5
.
Can be pulled greater than V
CC3
using an external pull-up.
COMP25 (Pin 7):
V
CC25
Comparator Output for the
LTC1727-2.5. Active high, open-drain logic output with
weak pull-up to V
CC3
. Asserted when V
CC25
is above
V
RT25
. Can be pulled greater than V
CC3
using an external
pull-up.
COMP3 (Pin 8):
V
CC3
Comparator Output for the LTC1727.
Active high, open-drain logic output with weak pull-up to
V
CC3
. Asserted when V
CC3
is above V
RT3
. Can be pulled
greater than V
CC3
using an external pull-up.
