Ultra-Low-Power Voltage Detectors and
µP Supervisory Circuits
The MAX6461–MAX6466 family of ultra-low-power voltage
detectors and µP reset supervisory circuits monitors battery, power-supply, and system voltages. Each circuit
includes a precision bandgap reference, a comparator,
internally trimmed resistor networks that set specified trip
thresholds, and an internal 5% threshold hysteresis circuit
(see the Functional Diagram). Output is asserted when
VCC falls below the internal VTH- and remains asserted
until VCC rises above VTH+ (VTH+ = VTH- × 1.05). These
devices provide excellent circuit reliability and low cost
by eliminating external components and adjustments
when monitoring nominal system voltages from +1.6V to
+5.5V. The MAX6461/MAX6462/MAX6463 are voltage
detectors with a propagation delay of 17µs.
The MAX6464/MAX6465/MAX6466 are µP supervisory
circuits with a minimum reset timeout period of 150ms. All
devices are available with thresholds from +1.6V to +5.5V
in 100mV increments.
The family is available with three output stage options:
push-pull with active-low output, push-pull with activehigh output, and open drain with active-low output. These
devices are available in SC70 and SOT23 packages
specified over the -40°C to +125°C temperature range.

The MAX6461–MAX6466 are available in factory-set thresholds
from 1.6V to 5.5V in approximately 100mV increments. Choose
the desired voltage threshold suffix from Table 1 and insert it in
the blank spaces in the part number. There are 30 standard versions with a required order increment of 2500 pieces. Sample
stock generally is held on the standard versions only (Table 2).
Nonstandard versions require a 10k-piece order increment.

OUT
Detector Output for the MAX6461/MAX6462/MAX6463: Push-pull (active-low or
active-high) and open-drain (active-low) options. OUT is asserted low when the
monitored input (VCC) drops below the internal VTH- threshold and remains low
until the monitored input exceeds the internal VTH+ threshold. OUT is asserted
high when the monitored input (VCC) drops below the internal VTH- threshold and
remains high until the monitored input exceeds the internal VTH+ threshold. The
open-drain output OUT requires an external pullup resistor. Output for the
MAX6464/MAX6465/MAX6466: Push-pull (active-low or active-high) and opendrain (active-low) options.
OUT
OUT is asserted low when the monitored input (VCC) drops below the internal
VTH- threshold and remains low for at least 150ms after the monitored input
exceeds the internal VTH+ threshold. OUT is asserted high when the monitored
input (VCC) drops below the internal VTH- threshold and remains high for at least
150ms after the monitored input exceeds the internal VTH+ threshold. The opendrain output OUT requires an external pullup resistor.

Detailed Description
The MAX6461/MAX6462/MAX6463 voltage detectors
and the MAX6464/MAX6465/MAX6466 µP reset supervisory circuits monitor battery, power-supply, and system
voltages from +1.6V to +5.5V. These devices consume
only 1µA of supply current with a 3.6V supply voltage.
Whenever VCC falls below the internal VTH- threshold,
the output is asserted and remains asserted until VCC
rises above VTH+ (VTH+ = VTH- × 1.05). All devices have
±2.5% threshold accuracy over temperature and offer
protection to short voltage transients. These devices are
ideal for low-cost and space-critical applications
because they do not require external components for
proper operation.

Applications Information
Interfacing to Different Logic Voltage
Components
The MAX6463 and MAX6466’s active-low, open-drain output versions can be used to interface with a different logic
voltage than VCC, as shown in Figure 1. This output structure sinks current when OUT is asserted. Connect a
pullup resistor from OUT to any supply from 0 to 6V.
Select a resistor value large enough to allow a valid logic
low (see the Electrical Characteristics) and small enough
to register a logic high while supplying all input current
and leakage paths connected to the OUT pin.
6
The MAX6461–MAX6466 feature internal hysteresis that
creates two trip points: one for rising supply voltage
and one for falling supply voltage. The hysteresis prevents the output from oscillating (chattering) when VCC
is near the voltage threshold.
Transients Immunity
These devices are relatively immune to short-duration
and falling V CC transients (glitches). The Typical
Operating Characteristics show the Maximum Transient
Duration vs. Threshold Overdrive graph, for which OUT
is not asserted. The graph shows the maximum pulse
width that a falling VCC transient typically might have
before the devices are asserted. As the amplitude of
the transient increases, the maximum allowable pulse
width decreases.
Ensuring Valid Output Down to 0V
When VCC falls below 1V, the MAX6461/MAX6464 output sinking capability is reduced. Therefore, highimpedance CMOS logic inputs connected to OUT can
drift to undetermined voltages. This presents no problem in most applications, because most circuitry is
inoperative when V CC is below 1V. In applications
where OUT must be valid down to ground, add a pulldown resistor to ground so any stray leakage currents
flow to ground, holding OUT low. Select a resistor large
enough not to load OUT and small enough to pull OUT
to ground. For most applications, 100kΩ does not load
OUT and pulls OUT to ground.

Package Information
For the latest package outline information, go to
www.maxim-ic.com/packages.)
The MAX6461–MAX6466 are available in factory-set thresholds
from 1.6V to 5.5V in approximately 100mV increments. Choose
the desired voltage threshold suffix from Table 1 and insert it in
the blank spaces in the part number. There are 30 standard versions with a required order increment of 2500 pieces. Sample
stock generally is held on the standard versions only (Table 2).
Nonstandard versions require a 10k-piece order increment.
Contact factory for availability. All devices available in tape-andreel only.
Maxim cannot assume responsibility for use of any circuitry other than circuitry entirely embodied in a Maxim product. No circuit patent licenses are
implied. Maxim reserves the right to change the circuitry and specifications without notice at any time.
