Low-Voltage, Quad-/Hex-/Octal-Voltage
µP Supervisors
–MAX1607
General Description
Features
The MAX16000–MAX16007 are low-voltage, quad-/hex-/
octal-voltage µP supervisors in small thin QFN and TSSOP
packages. These devices provide supervisory functions for
complex multivoltage systems. The MAX16000/
MAX16001/MAX16002 monitor four voltages, the
MAX16003/MAX16004/MAX16005 monitor six voltages,
and the MAX16006/MAX16007 monitor eight voltages.
o Fixed Thresholds for 5V, 3.3V, 3V, 2.5V, 1.8V,
1.5V, 1.2V, and 0.9V Systems
o Adjustable Thresholds Monitor Voltages Down to
0.4V
o Open-Drain Outputs with Internal Pullups Reduce
the Number of External Components
o Fixed 140ms (min) or Capacitor-Adjustable Reset
Timeout
The MAX16000/MAX16001/MAX16003/MAX16004/
MAX16006 offer independent outputs for each moni-
tored voltage. The MAX16001/MAX16002/MAX16004–
MAX16007 offer a reset output that asserts whenever
any of the monitored voltages fall below their respective
thresholds or the manual reset input is asserted. The
reset output remains asserted for the reset timeout after
all voltages are above their respective thresholds and
the manual reset input is deasserted. The minimum
reset timeout is internally set to 140ms or can be adjust-
ed with an external capacitor.
o Manual Reset, Margin Enable, and Tolerance
Select Inputs
o Watchdog Timer
1.6s (typ) Timeout Period
54s Startup Delay After Reset (Except MAX16005)
o Independent Watchdog Output (MAX16005)
o RESET Output Indicates All Voltages Present
o Independent Voltage Monitors
All open-drain outputs have internal 30µA pullups that
eliminate the need for external pullup resistors.
However, each output can be driven with an external
voltage up to 5.5V. Other features offered include a
manual reset input, a tolerance pin for selecting 5% or
10% input thresholds, and a margin enable function for
deasserting the outputs during margin testing.
o Guaranteed Correct Logic State Down to V = 1V

o Small (4mm x 4mm) Thin QFN Package
o TSSOP (5mm x 4.4mm) Package (MAX16005)

TEMP RANGE
PIN-PACKAGE
The MAX16001/MAX16002/MAX16004–MAX16007 offer
a watchdog timer that asserts RESET or an indepen-
dent watchdog output (MAX16005) when the watchdog
timeout period (1.6s typ) is exceeded. The watchdog
timer can be disabled by floating the input.

For tape-and-reel, add a “T” after the “+.” Tape-and-reel are
offered in 2.5k increments.
These devices are offered in 12-, 16-, 20-, and 24-lead
thin QFN and 16-lead TSSOP packages. These are fully

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.

WDI
CC
Watchdog Timer Input. If WDI remains low or high for longer than the watchdog timeout period,
RESET is asserted. The timer clears whenever a reset is asserted or a rising or falling edge on
WDI is detected. The watchdog timer enters a startup period that allows 54s for the first
transition to occur before a reset. Leave WDI unconnected to disable the watchdog timer. The
WDI floating-state detector uses a small 400nA current. Therefore, do not connect WDI to
anything that will source or sink more than 200nA. Note that the leakage current specification for
most three-state drivers exceeds 200nA.
Active-Low Manual Reset Input. Pull MR low to assert RESET low. RESET remains low for the

reset timeout period after MR is deasserted. MR is pulled up to V
through a 20kΩ resistor.
CC
Set Reset Timeout Input. Connect a capacitor from SRT to GND to set the reset timeout period.
The reset timeout period can be calculated as follows:
6
SRT
Reset Timeout (s) = 2.06 x 10 (Ω) x C
(F). For the internal timeout period of 140ms (min),
SRT
connect SRT to V
.
CC
Active-Low Reset Output. RESET asserts low when any of the monitored voltages falls below its
respective threshold or MR is asserted. RESET remains asserted for the reset timeout period
after all monitored voltages exceed their respective thresholds and MR is deasserted. This
open-drain output has a 30µA internal pullup.

Window Detection
Detailed Description
A window detector circuit uses two auxiliary inputs in
the configuration shown in Figure 8. External resistors
set the two threshold voltages of the window detector
circuit. External logic gates create the OUT signal. The
window detection width is the difference between the
threshold voltages (Figure 9).
The MAX16000–MAX16007 are low-voltage, quad-/hex-/
octal-voltage µP supervisors in small thin QFN and TSSOP
packages. These devices provide supervisory functions
for complex multivoltage systems. The MAX16000/
MAX16001/MAX16002 monitor four voltages, the
MAX16003/MAX16004/MAX16005 monitor six voltages,
and the MAX16006/MAX16007 monitor eight voltages.
The MAX16000/MAX16001/MAX16003/MAX16004/
MAX16006 offer independent outputs for each moni-
tored voltage. The MAX16001/MAX16002/MAX16004–
MAX16007 offer a reset output that asserts whenever
any of the monitored voltages fall below their respective
thresholds or the manual reset input is asserted. The
reset output remains asserted for the reset timeout after
all voltages are above their respective thresholds and
the manual reset input is deasserted. The minimum
reset timeout is internally set to 140ms or can be
adjusted with an external capacitor.

All open-drain outputs have internal 30µA pullups that
eliminate the need for external pullup resistors.
However, each output can be driven with an external
voltage up to 5.5V. Other features offered include a
manual reset input, a tolerance pin for selecting 5% or
10% input thresholds, and a margin enable function for
deasserting the outputs during margin testing.

dent watchdog output (MAX16005) when the watchdog

WDO (MAX16005 Only)
WDO asserts and stays low whenever any of the IN_
inputs fall below their respective thresholds. WDO
deasserts without a timeout delay when all the IN_
inputs rise above their thresholds. When all the IN_
inputs rise above their thresholds, WDO asserts low
whenever the watchdog timer times out. WDO
deasserts after a valid WDI transition or if MR is pulled
low. The watchdog timer begins counting after the reset
timeout period once MR goes high. Pull MARGIN low to
deassert WDO regardless of any other condition. The
watchdog timer continues to run when MARGIN is low
and if a timeout occurs. WDO will assert MR after
MARGIN is deasserted. This open-drain output has a

Reset Timeout Capacitor
The reset timeout period can be adjusted to accommo-
date a variety of µP applications from 50µs to 1.12s.
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 environ-
ment, connecting a 0.1µF capacitor from MR to GND
provides additional noise immunity.
Adjust the reset timeout period (t ) by connecting a
RP
capacitor (C
) between SRT and GND. Calculate the
SRT
reset timeout capacitor as follows:
Margin Output Disable (MARGIN)
MARGIN allows system-level testing while power sup-
plies are adjusted from their nominal voltages. Drive
MARGIN low to force RESET, WDO, and OUT_ high,
regardless of the voltage at any monitored input. The
state of each output does not change while MARGIN =
GND. The watchdog timer continues to run when
MARGIN is low, and if a timeout occurs, WDO/RESET

Many µP-based products require manual reset capabil-
ity, allowing the operator, a test technician, or external
logic circuitry to initiate a reset. A logic-low on MR
asserts RESET low. RESET remains asserted while MR
is low, and during the reset timeout period (140ms min)
after MR returns high. The MR input has an internal
Power-Supply Bypassing
The MAX16000–MAX16007 operate from a 2.0V to 5.5V
supply. An undervoltage lockout ensures that the out-
puts are in the correct states when the UVLO is exceed-
ed. In noisy applications, bypass V

0.1µF capacitor as close to the device as possible. The
additional capacitor improves transient immunity. For
