Active-Low Reset Output. Open drain for the MAX6352/
MAX6355/MAX6358, push-pull with respect to V

Ground
Manual-Reset Input. Pull low to force a reset. RST,
RST1, and RST2 remain active as long as MR is low
and for the timeout period after MR goes high.

Active-Low, CMOS Reset Output Referenced to V
Undervoltage Reset Comparator Input. Asserts
reset when the monitored voltage falls below 1.22V.
Set the reset threshold with an external resistive
divider. Connect to V

Watchdog Input. If WDI remains either high or low
longer than the timeout period, then reset is trig-
gered. The timer clears when reset is asserted or
whenever WDI sees a rising or falling edge. Leave
floating to disable it if unused.
