PIN DESCRIPTION
RESET/
RESET
RESET:
RESET OUTPUTS
(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 be 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.
VSENSE: AUXILIARY VOLTAGE MONITOR INPUT
The VSENSE 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
VLOW output will be driven low. An external resistor
divider is used to set the voltage level to be sensed.
Connect V
SENSE to VCC 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.
