NAME
FUNCTION

1
MR
Active-Low, Manual Reset Input, Internal 50k
Pullup to VCC.
Pull low to force a reset. Reset remains active as long as MR is
low and the reset timeout period after MR goes high. Leave
unconnected or connect to VCC if unused. WDO deasserts
when MR is low (MAX6701(A)/MAX6702(A)/MAX6703(A)/
MAX6705(A)/ MAX6706(A)/MAX6707(A) only).

2
VCC
Supply Voltage for MAX6701–MAX6708 and Input for Primary
Reset Threshold Monitor. Push-pull outputs are powered by VCC
.
3
GND
Ground

4
PFI
Power-Fail Voltage Monitor Input. High-impedance input for
internal power-fail comparator. Connect this pin to an external
resistive-divider network to set the reset threshold voltage;
0.62V (typ) threshold. Connect to GND or VCC when not used.

PFO
Power-Fail Monitor Output. Open drain or push-pull active low.
PFO goes low when PFI is less than 0.62V.

WDI
Watchdog Input. If WDI remains high or low for longer than the
watchdog timeout period, the internal watchdog timer runs out and
WDO is asserted. WDO is asserted low after each watchdog
overflow and remains low until the watchdog timer is cleared (the
reset output is not affected). The internal watchdog timer clears
whenever a VCC/RST_IN1/RST_IN2 reset is asserted, the manual
reset is asserted, or WDI sees a rising or falling edge. The
watchdog timer remains cleared until the reset output is
deasserted. On the MAX6704, RESET pulse asserts for the reset
timeout period after each watchdog timeout overflow. The
watchdog timer cannot be disabled.

N.C.
No Connection. Not internally connected.

RESET
Active-Low Reset Output (Open Drain or Push-Pull). RESET
changes from high to low when the VCC input drops below the
selected reset threshold (or RST_IN1/ RST_IN2 for the
MAX6701(A)/MAX6702(A)/MAX6703(A), MR is pulled low, or the
watchdog triggers a reset (MAX6704 only). RESET remains low for
the reset timeout period after the reset conditions are terminated.
