Pin Description

Pin Number

Pin Name

Pin Function

1

NC

Not Internally Connected.

2

VDD

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

3

GND

Ground.

4

VIN

Analog (Input). Monitored input voltage. An under-voltage condition will trigger a reset sequence.

5

/MR

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.

6

/RST

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.
