FUNCTION

Active-Low Reset Output,

Open-Drain or Push-Pull.

RST2 changes from high

to low when VCC1 or

VCC2 drops below the

selected reset thresholds

or MR is pulled low. RST2

remains low for the reset

timeout period after

VCC1/VCC2 exceed the

device reset thresholds

or MR goes low to high.

Open-drain outputs

require an external pullup

resistor. Push-pull

outputs are referenced to

VCC2.

Ground

Active-Low Manual Reset

Input. Internal 50kΩ

pullup to VCC1. Pull low

to force a reset. Reset

remains active as long as

MR is low and for the

reset timeout period after

MR goes high. Leave

unconnected or connect

to VCC1 if unused.

Secondary Supply

Voltage Input. Powers the

device when it is above

VCC1 and input for

secondary reset

threshold monitor.

Primary Supply Voltage

Input. Powers the device

when it is above VCC2

and input for primary

reset threshold monitor.
