RST2

Active-Low Reset Output,

Open-Drain or Push-Pull.

RST2 changes from high

drops below the selected

reset thresholds or MR is

pulled low. RST2 remains

low for the reset timeout

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
