Pin Function
Digital (Output): Asserted high whenever V
voltage. It will remain asserted for no less than 140ms after V
above the threshold limit.
Ground
Digital (Output): Asserted low whenever V
voltage. It will remain asserted for no less than 140ms after V
above the threshold limit.
Digital (Input): Driving this pin low initiates an immediate and unconditional
reset. Assuming V
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
Analog (Input): Power supply input and the voltage being monitored.
