PG8
IN8 is below the pin-selectable/adjustable input threshold or ENABLE is pulled
high. PG8 deasserts with a factory preset timeout period of 6.25ms.
Open-Drain, Active-Low Reset Output Stage. RESET asserts low when any

RESET
monitored input (IN_) is below the selected threshold or manual reset ( MR ) is
pulled low. RESET remains low for the reset timeout period after all reset-
causing conditions are cleared, and then deasserts.
Open-Drain, Active-Low Watchdog Output Stage. If WDI remains high or low for
longer than the watchdog timeout period, the internal watchdog timer runs out

WDO
and the WDO output asserts low. The internal watchdog timer clears whenever
RESET is asserted or WDI sees a rising or falling edge. Connect WDO to MR to
automatically assert the RESET output after each watchdog timeout fault.
Margin Input. MARGIN holds PG_, RESET , and WDO in their existing states

MARGIN
when driven low. Leave MARGIN unconnected or connect to DBP if unused.
MARGIN overrides MR if both assert at the same time. MARGIN is internally
pulled up to DBP through a 10μA current source.
Active-Low Manual Reset Input. Pull MR low to assert RESET . RESET remains

MR
asserted for its preset/adjustable reset timeout period when MR is driven/pulled
high. MR is internally pulled up to DBP through a 10μA current source.
Threshold Selection Input 0. Logic input to select desired thresholds. Connect

TH0
TH0 to GND or DBP. See Table 2 for available thresholds. Input has no internal
pullup or pulldown.
