VCC3 (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 VCC3 is greater than the voltage on
VCC5/VCC25/VCC18. Bypass to ground with a ≥ 0.1F
ceramic capacitor.
VCC5 (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 VCC5 is
greater than the voltage on VCC3. Bypass to ground with
a
≥0.1F ceramic capacitor.
VCC25 (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 VCC25 is
greater than the voltage on VCC3. Bypass to ground with
a
≥0.1F ceramic capacitor.
VCC18 (Pin 2/Pin 4): 1.8V Sense Input and Power Supply
Pin. This pin is used on the LTC1728-1.8/LTC1728-3.3 to
provide power to the part when the voltage on VCC18 is
greater than the voltage on VCC3. Bypass to ground with
a
≥0.1F ceramic capacitor.
VCCA (Pin 3/Pin 3): 1V Sense, High Impedance Input. If
unused, it can be tied to either VCC3 or VCC5/VCC25/VCC18.
GND (Pin 4/Pin 2): Ground.
COMPA (Pin 5): VCCAComparatorOutputfortheLTC1727.
Active high, open-drain logic output with weak pull-up to
VCC3. Asserted when VCCA is above VRTA. Deasserted
when VCCA is below VRTA or if both the VCC3 and VCC5
supply pins are too low to power the internal bandgap
reference (typically < 2.0V). Can be pulled greater than
VCC3 using an external pull-up.
RST (Pin 6/Pin 1): Reset Logic Output. Active low, open-
drain logic output with weak pull-up to VCC3. Can be pulled
up greater than VCC3 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): VCC5 Comparator Output for the
LTC1727-5. Active high, open-drain logic output with
weak pull-up to VCC3. Asserted when VCC5 is above VRT5.
Can be pulled greater than VCC3 using an external pull-up.
COMP25 (Pin 7): VCC25 Comparator Output for the
LTC1727-2.5. Active high, open-drain logic output with
weak pull-up to VCC3. Asserted when VCC25 is above
VRT25. Can be pulled greater than VCC3 using an external
pull-up.
COMP3 (Pin 8): VCC3 ComparatorOutputfortheLTC1727.
Active high, open-drain logic output with weak pull-up to
VCC3. Asserted when VCC3 is above VRT3. Can be pulled
greater than VCC3 using an external pull-up.
