Pin Name
Pin Function
1
RST
Digital (Output): Asserted high whenever V
IN
or V
DD
falls below the thresh-
old voltage. It will remain asserted for no less than 140ms after V
IN
and V
DD
return above the threshold limits.

/RST
Digital (Output): Asserted low whenever V
IN
or V
DD
falls below the threshold
voltage. It will remain asserted for no less than 140ms after V
IN
and V
DD
return above the threshold limits. (open-drain for

version)

/MR
Digital (Input): Driving this pin low initiates immediate and unconditional
reset. Assuming V
IN
and V
DD
are above the thresholds 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.

IN

5
VDD
Analog (Input): Power supply input for internal circuitry and input to the fixed
voltage monitor. The voltage on this pin is compared against the internal
reference. An undervoltage condition will trigger a reset sequence.
