Active-High Reset Output. RESET is continuously high when V
low, or RESET IN is low. It asserts in pulses when the internal watchdog times out. RESET remains high
for the reset timeout period (t
goes from low to high, after RESET IN goes high, or after the watchdog triggers a reset event. The
MAX636_H is an active-high open-drain output.
Active-Low Reset Output. RESET is continuously low when V
low, or RESET IN is low. It asserts in pulses when the internal watchdog times out. RESET remains low for
the reset timeout period (t
from low to high, after RESET IN goes high, or after the watchdog triggers a reset event. The MAX636_L
is an active-low push-pull output while the MAX636_P is an active-low open-drain output.

MAX6361 Manual-Reset Input. Maintaining logic low on MR asserts a reset. Reset output remains assert-

MAX6362 Watchdog Input. If WDI remains high or low for longer than the watchdog timeout period (t
internal watchdog timer runs out and a reset pulse is triggered for the reset timeout period (t
internal watchdog clears whenever reset asserts or whenever WDI sees a rising or falling edge.
MAX6363 Battery-On Output. BATT ON goes high in battery backup mode.
MAX6364 Reset Input. When RESET IN falls below 1.235V, reset is asserted. Reset output remains
asserted as long as RESET IN is low and for at least 150ms (t
