Pin Function
Digital (Output): Asserted low whenever V IN or V DD falls below the reference
voltage. It will remain asserted for no less than 140ms after V IN and V DD
return above the threshold limits.
Ground
Digital (Output): Asserted high whenever V IN or V DD falls below the refer-
ence voltage. It will remain asserted for no less than 140ms after V IN and
V DD return within above the threshold limit.
Analog (Input): The voltage on this pin is compared to the internal 300mV
reference. An undervoltage condition will trigger a reset sequence. Manual
reset capability can be achieved by adding a switch between this pin and
ground.
Analog (Input): Power supply input for internal circuitry and input to the ?xed
voltage monitor: The voltage on this pin is compared against the internal
voltage reference. An undervoltage condition will trigger a reset sequence.
