Pin Description
Pin Number
Pin Name
Pin Function
1
RST
Digital (Output): Asserted high whenever V
DD
falls below the reference
voltage. It will remain asserted for no less than 140ms after V
DD
returns
above the threshold limit.
2
GND
Ground
3
/RST
Digital (Output): Asserted low whenever V
DD
falls below the reference
voltage. It will remain asserted for no less than 140ms after V
DD
returns
above the threshold limit.
4
/MR
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.
