MAX6381–MAX6390
SC70/μDFN, Single/Dual Low-Voltage,
Low-Power μP Reset Circuits
General Description
The MAX6381–MAX6390 microprocessor (μP) supervi-
sory circuits monitor power-supply voltages from +1.8V
to +5.0V while consuming only 3μA of supply current at
Features
● Factory-Set Reset Threshold Voltages Ranging from
+1.58V to +4.63V in Approximately 100mV Increments
● ±2.5% Reset Threshold Accuracy Over
Temperature (-40°C to +125°C)
+1.8V. Whenever V
falls below the factory-set reset
CC
thresholds, the reset output asserts and remains asserted
for a minimum reset timeout period after V rises above
the reset threshold. Reset thresholds are available from
+1.58V to +4.63V, in approximately 100mV increments.
Seven minimum reset timeout delays ranging from 1ms
to 1200ms are available.
● Seven Reset Timeout Periods Available: 1ms, 20ms,
140ms, 280ms, 560ms, 1120ms, 1200ms (min)
CC
● 3 Reset Output Options
• Active-Low Push-Pull
• Active-High Push-Pull
• Active-Low Open-Drain
TheMAX6381/MAX6384/MAX6387haveapush-pullactive-
low reset output. The MAX6382/MAX6385/MAX6388 have
a push-pull active-high reset output, and the MAX6383/
MAX6386/MAX6389/MAX6390 have an open-drain active-
low reset output. The MAX6384/MAX6385/MAX6386 also
feature a debounced manual reset input (with internal
pullup resistor). The MAX6387/MAX6388/MAX6389 have
an auxiliary input for monitoring a second voltage. The

MAX6390 offers a manual reset input with a longer V
reset timeout period (1120ms or 1200ms) and a shorter
manual reset timeout (140ms or 150ms).

Reset asserts when V
is below the reset threshold;
CC
once V
exceeds the reset threshold, an internal timer
CC
keeps the reset output asserted for the reset timeout
period. After this interval, reset output deasserts. Reset
output is guaranteed to be in the correct logic state for
V
CC
≥ 1V.
Manual Reset Input (MAX6384/
MAX6385/MAX6386/MAX6390)
Many μP-based products require manual reset capability,
allowing the operator, a test technician, or external logic
circuitry to initiate a reset. A logic low on MR asserts reset.
Reset remains asserted while MR is low, and for the reset
active timeout period (t ) after MR returns high. This
RP
input has an internal 63kΩ pullup resistor (1.56kΩ for
MAX6390), so it can be left unconnected if it is not used.
MR can be driven with TTL or CMOS logic levels, or with
open-drain/collector outputs. Connect a normally open
momentary switch from MR to GND to create a manual-
reset function; external debounce circuitry is not required.
If MR is driven from long cables or if the device is used in
a noisy environment, connecting a 0.1μF capacitor from
MR to GND provides additional noise immunity.
RESET IN Comparator
(MAX6387/MAX6388/MAX6389)
RESET IN is compared to an internal +1.27V reference. If
the voltage at RESET IN is less than 1.27V, reset asserts.
Use the RESET IN comparator as a user-adjustable
reset detector or as a secondary power-supply monitor
by implementing a resistor-divider at RESET IN (shown
in Figure 1). Reset asserts when either V
or RESET
CC
IN falls below its respective threshold voltage. Use the
following equation to set the threshold:

In addition to issuing a reset to the μP during power-up,

Since the input current at RESET IN is 50nA (max), large
