NAME

FUNCTION

1, 4

RST/

RST1

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/RST1 remains

low for 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.
