thresholds are available. However, Xicor’s unique circuits
allow the threshold to be reprogrammed to meet custom
requirements or to fine-tune the threshold for applications
requiring higher precision.

sense level for typically 200ms. RESET goes active if the Watchdog Timer is
enabled and SDA remains either HIGH or LOW longer than the selectable Watchdog time-
out period. A falling edge on SDA, while SCL is HIGH, resets the Watchdog Timer. RESET
goes active on power up and remains active for typically 200ms after the power supply
stabilizes.
Ground
Serial Data.
SDA is a bidirectional pin used to transfer data into and out of the device. It has
an open drain output and may be wire ORed with other open drain or open collector outputs.
This pin requires a pull up resistor and the input buffer is always active (not gated).
Watchdog Input.
A HIGH to LOW transition on the SDA (while SCL is HIGH) restarts the
Watchdog timer. The absence of a HIGH to LOW transition within the watchdog time-out
period results in RESET going active.
Serial Clock.
The Serial Clock controls the serial bus timing for data input and output.
V2 Voltage Fail Output.
This open drain output goes LOW when V2MON is less than
V
TRIP2
and goes HIGH when V2MON exceeds V
circuitry on this pin. This circuit works independently from the Low V
switch circuits. Connect V2FAIL to VSS when not used.
V2 Voltage Monitor Input.
When the V2MON input is less than the V
goes LOW. This input can monitor an unregulated power supply with an external resistor
divider or can monitor a second power supply with no external components. Connect
V2MON to V

when not used. There is no hysteresis in the V2MON comparator
