RST2

Active-Low Reset Output,

Open-Drain or Push-Pull.

RST2 changes from high

selected reset thresholds

or

MR is pulled low. RST2

remains low for the reset

timeout period after

device reset thresholds

or

MR goes low to high.

Open-drain outputs

require an external pullup

resistor. Push-pull

outputs are referenced to

MR is low and for the

reset timeout period after

MR goes high. Leave
