Manual Reset Input. Pulling the MR pin LOW initiates a system reset. The RESET/RESET pin will remain HIGH/LOW

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 toggled from HIGH to LOW and followed by a stop
condition) restarts the Watchdog timer. The absence of this transition within the watchdog time out period results in WDO
going active.
Serial Clock. The Serial Clock controls the serial bus timing for data input and output.
Write Protect. WP HIGH prevents writes to any location in the device (including all the registers). It has an internal
pull-down resistor (>10MΩ typical).
V3 Voltage Monitor Input. When the V3MON input is less than the V
monitor an unregulated power supply with an external resistor divider or can monitor a third power supply with no external
components. Connect V3MON to V
V3 Voltage Fail Output. This open drain output goes LOW when V3MON is less than V
V3MON exceeds V
WDO Output. WDO is an active LOW, open drain output, which goes active whenever the watchdog timer goes active.
