PIN DESCRIPTION
RESET/
(RESET CAT1026 Only)
These are open drain pins and ˉˉˉˉˉˉ can be used
as a manual reset trigger input. By forcing a reset
condition on the pin the device will initiate and
maintain a reset condition. The RESET pin must be
connected through a pull-down resistor, and the
RESET
ˉˉˉˉˉˉ pin must be connected through a pull-up
resistor.

RESET OUTPUTs
SDA:
SERIAL DATA ADDRESS
The bidirectional serial data/address pin is used to
transfer all data into and out of the device. The SDA
pin is an open drain output and can be wire-ORed
with other open drain or open collector outputs.
SCL:
SERIAL CLOCK
Serial clock input.
V
SENSE
:
AUXILIARY VOLTAGE MONITOR INPUT
The V
SENSE
input is a second voltage monitor which is
compared against CAT1026 and CAT1027 internal
reference voltage of 1.25V typically. Whenever the
input voltage is lower than 1.25V, the open drain V
LOW
output will be driven low. An external resistor divider is
used to set the voltage level to be sensed. Connect
V
SENSE
to V
CC
if unused.
V
LOW
:
AUXILIARY VOLTAGE MONITOR OUTPUT
This open drain output goes low when V
SENSE
is less
than 1.25V and goes high when V
SENSE
exceeds the
reference voltage.
WDI (CAT1027 Only):
WATCHDOG TIMER INTERRUPT
Watchdog Timer Interrupt Input is used to reset the
watchdog timer. If a transition from high to low or low
to high does not occur every 1.6 seconds, the RESET
outputs will be driven active.
