Pin Function
Digital (Output): Asserted low whenever V_DD falls below the reference volt-
age. It will remain asserted for no less than 140ms after V_DD returns above
the threshold limit.
Ground
Digital (Output): Asserted high whenever V_DD falls below the reference volt-
age. It will remain asserted for no less than 140ms after V_DD returns above
the threshold limit.
Digital (Input): Driving this pin low initiates an immediate and unconditional
reset. Assuming V_DD is above the threshold when /MR is released (returns
high), the reset output will be de-asserted no less than 140ms later. /MR
may be driven by a logic signal or a mechanical switch. /MR has an internal
pull-up to V_DD and may be left open if unused.
Analog (Input): Power supply input and the voltage being monitored.
