NAME
FUNCTION
Active-Low Watchdog Output (Open Drain or Push-Pull). WDO
is asserted whenever the watchdog times out and V CC or the
reset inputs are below their respective thresholds. WDO
deasserts after a valid WDI transition without a reset timeout

period. In the A versions, WDO deasserts without a timeout
delay when V CC , RST_IN1, and RST_IN2 rises above its
threshold. Pull MR low to assert WDO (MAX6701/MAX6702/
MAX6703/MAX6705/MAX6706/MAX6707 only). Pull MR low to
deassert WDO (MAX6701(A)/MAX6702(A)/MAX6703(A)/
MAX6705(A)/MAX6706(A)MAX6707(A) only).

to high when the V CC input drops below the selected reset

timeout period after the reset conditions are terminated.

Detailed Description
Figures 1, 2, and 3 are functional diagrams for the
MAX6705(A)/MAX6706(A)/MAX6707(A), MAX6704/
MAX6708, and MAX6701(A)/ MAX6702(A)/MAX6703(A),
respectively.
Reset Output
A microprocessor ’ s (μP ’ s) reset input starts the μP in a
known state. The MAX6701 – MAX6708 assert reset dur-
ing power-up and prevent code execution errors during
power-down or brownout conditions.
On power-up, once V CC reaches 1V, RESET is a guar-
anteed logic low of 0.4V or less. As V CC rises, RESET
stays low. After V CC , RST_IN1, or RST_IN2 rise above
the reset threshold, an internal timer holds RESET low
for about 200ms. RESET pulses low whenever V CC dips
below the reset threshold, including brownout condi-
tions. If a brownout occurs in the middle of a previously
initiated reset pulse, the pulse continues for at least
another 140ms. On power-down, once V CC falls below
the reset threshold, RESET stays low and is guaranteed
to be 0.4V or less, until V CC drops below 1V.
The MAX6702(A)/MAX6704/MAX6706(A)/MAX6708
active-high RESET output is the complement of the
RESET output, and is guaranteed to be valid with V CC
down to 1V.
