NAME

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

RST2 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.
