Pin Function
Digital (Output): Asserted high whenever V_IN falls below the reference volt-
age. It will remain asserted for no less than 140ms after V_IN returns above
the threshold limit.
Digital (Output): Asserted low whenever V_IN falls below the reference volt-
age. It will remain asserted for no less than 140ms after V_IN returns above
the threshold limit. (open-drain for “N” version)
Ground
Digital (Input): Driving this pin low initiates an immediate and unconditional
reset. Assuming IN 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): The voltage on this pin is compared to the internal 300mV
reference. An under-voltage condition will trigger a reset sequence.
Analog (Input): Independent supply input for internal circuitry.
