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.
