MAX6316M/MAX6318MH/MAX6319MH:
Bidirectional, Active-Low, Reset Output.
Intended to interface directly to microprocessors
with bidirectional resets such as the Motorola
68HC11.
MAX6320P/MAX6321HP/MAX6322HP:
Open-Drain, Active-Low, Reset Output. NMOS out-
put (sinks current only). Connect a pullup resistor
from RESET to any supply voltage up to 6V.
MAX6316L/MAX6318LH/MAX6319LH:
Active-Low, Reset Output. CMOS push/pull
output (sources and sinks current).

MAX6317H
Active-Low, Manual Reset Input. Pull low to force a
reset. Reset remains asserted for the duration of
the Reset Timeout Period after MR transitions from
low to high. Leave unconnected or connected to
VCC if not used.
MR
3
Watchdog Input. Triggers a reset if it remains
either high or low for the duration of the watchdog
timeout period. The internal watchdog timer clears
whenever a reset asserts or whenever WDI sees a
rising or falling edge. To disable the watchdog fea-
ture, leave WDI unconnected or three-state the dri-
ver connected to WDI.
WDI
4
Supply Voltage. Reset is asserted when VCC
drops below the Reset Threshold Voltage (VRST).
Reset remains asserted until VCC rises above
VRST and for the duration of the Reset Timeout
Period (tRP) once VCC rises above VRST.
VCC
5
Active-High, Reset Output. CMOS push/pull output
(sources and sinks current). Inverse of RESET.
