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 (P’s) reset input starts the P 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 VCC reaches 1V, RESET is a guar-
anteed logic low of 0.4V or less. As VCC rises, RESET
stays low. After VCC, RST_IN1, or RST_IN2 rise above
the reset threshold, an internal timer holds RESET low
for about 200ms. RESET pulses low whenever VCC 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 VCC falls below
the reset threshold, RESET stays low and is guaranteed
to be 0.4V or less, until VCC 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 VCC
down to 1V.

WDO
Active-Low Watchdog Output (Open Drain or Push-Pull). WDO
is asserted whenever the watchdog times out and VCC 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 VCC, 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).

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

RST_IN1
Input for User-Adjustable VCC2 Monitor. High-impedance input
for second internal reset comparator. Connect this pin to an
external resistive-divider network to set the reset threshold
voltage; 0.62V (typ) threshold. Connect to VCC when not used.
Reset is asserted when either VCC, RST_IN1, or RST_IN2 are
below threshold.

RST_IN2
Input for User-Adjustable VCC3 Monitor. High-impedance input
for third internal reset comparator. Connect this pin to an
external resistive-divider network to set the reset threshold
voltage; 0.62V (typ) threshold. Connect to VCC when not used.
Reset is asserted when either VCC, RST_IN1, or RST_IN2 are
below threshold.
*RESET active-high for the MAX6702(A)/MAX6706(A).
