Pin Function
Not Internally Connected.
Analog (Input). Independent supply input for internal circuitry.
Ground.
Analog (Input). Monitored input voltage. An under-voltage condition will trigger a reset sequence.
Digital (Input): Asserting this pin low initiates an immediate and unconditional reset. Assuming VIN
is above the threshold when /MR is released (returns high), the reset output will be de-asserted.
/MR may be driven by a logic signal or a mechanical switch. /MR has an internal pull-up to VDD
and may be left floating if unused.
Digital (Output): Asserted low whenever the VIN pin voltage falls below the reference voltage or
Manual Reset pin (/MR) is asserted. It will remain asserted until VIN voltage rises above the
threshold voltage and the /MR pin is released. The maximum output voltage of the /RST pin is
VIN. /RST is a push-pull output.
