1

RST

Digital (Output): Asserted high whenever V

voltage. It will remain asserted for no less than 140ms after V

above the threshold limit.

1

/RST

Digital (Output): Asserted low whenever V

voltage. It will remain asserted for no less than 140ms after V

above the threshold limit. (open-drain for “N” version)

2

GND

Ground

3

3

/MR

Digital (Input): Driving this pin low initiates an immediate and unconditional

reset. Assuming IN 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

IN

Analog (Input): The voltage on this pin is compared to the internal 300mV

reference. An under-voltage condition will trigger a reset sequence.

VDD

Analog (Input): Independent supply input for internal circuitry.
