PIN DESCRIPTION
RESET/RESET : RESET OUTPUTs
Table 2. PIN FUNCTION
(RESET CAT1026 Only)
These are open drain pins and RESET 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 b e connected through a pull ? down
resistor, and the RESET pin must be connected through a
pull ? up resistor.
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.

(CAT1027 Only)
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 1.25 V typically. Whenever the input
voltage is lower than 1.25 V, 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
1.25 V 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.
