NAME

FUNCTION

Active-Low Reset Output,

Open-Drain or Push-Pull.

RST/RST1 changes from

high to low when VCC1

or VCC2 drops below the

selected reset thresholds,

RSTIN is below threshold,

MR is pulled low, or the

watchdog triggers a reset.

RST/ RST/RST1 remains low for

RST1 the reset timeout period

after VCC1/VCC2/RSTIN

exceed the device reset

thresholds, MR goes low

to high, or the watchdog

triggers a reset. Open-

drain outputs require an

external pullup resistor.

Push-pull outputs are

referenced to VCC1.
