General Description
The MAX6406–MAX6411 is a family of ultra-low power
circuits used for monitoring battery, power-supply, and
regulated system voltages. Each detector contains a
precision bandgap reference comparator and is
trimmed to specified trip threshold voltages. These
devices provide excellent circuit reliability and low cost
by eliminating external components and adjustments
when monitoring system voltages from 2.5V to 5.0V. A
manual reset input is also included.
The MAX6406–MAX6411 assert a signal whenever the
VCCsupply voltage falls below a preset threshold.
These devices are differentiated by their output logic
configurations and preset threshold voltages. The
MAX6406/MAX6409 (push-pull) and the MAX6408/
MAX6411 (open-drain) have an active-low output (OUT
is logic low when VCCis below VTH). The MAX6407/
MAX6410 have an active-high push-pull output (OUT
is logic high when VCCis below VTH). All parts are
guaranteed to be in the correct output logic state for
VCCdown to 1V. The detector is designed to ignore
fast transients on VCC. The MAX6406/MAX6407/
MAX6408 have voltage thresholds between 2.20V and
3.08V in approximately 100mV increments. The
MAX6409/MAX6410/MAX6411 have voltage thresholds
between 3.30V and 4.63V in approximately 100mV
increments.
Ultra-low supply current of 500nA (MAX6406/MAX6407/
MAX6408) makes these parts ideal for use in portable
equipment. These devices are available in 4-bump
chip-scale packages (UCSP).

Detailed Description
Manual Reset Input
Many µP-based products require manual reset capability, allowing the operator, a test technician, or external
logic circuit to initiate a reset. A logic low on MR asserts
OUT/OUT. OUT/OUT remains asserted while MR is low.
This input has an internal 50kΩ pullup resistor, so it can
be left open 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. If MR is
driven from long cables or if the device is used in a
noisy environment, connect a 0.1µF capacitor from MR
to ground to provide additional noise immunity.
Applications Information
Interfacing to Different Logic
Voltage Components
The MAX6408/MAX6411 have an active-low, opendrain output. This output structure will sink current
when OUT is asserted. Connect a pullup resistor from
OUT to any supply voltage up to 5.5V (Figure 1). Select
a resistor value large enough to allow a valid logic low
(see Electrical Characteristics), and small enough to
register a logic high while supplying all input currents
and leakage paths connected to the OUT line.

Negative-Going VCCTransients
These devices are relatively immune to short-duration,
negative-going VCCtransients (glitches).
The Typical Operating Characteristics show the
Maximum Transient Duration vs. Threshold Overdrive
graph, for which output pulses are not generated. The
graph shows the maximum pulse width that a negativegoing VCCtransient may typically have before the
devices issue output signals. As the amplitude of the
transient increases, the maximum allowable pulse width
decreases.
UCSP Reliability
The chip-scale package (UCSP) represents a unique
packaging form factor that may not perform equally to a
packaged product through traditional mechanical reliability tests. CSP reliability is integrally linked to the user’s
assembly methods, circuit board material, and usage
environment. The user should closely review these areas
when considering use of a CSP package. Performance
through Operating Life Test and Moisture Resistance
remains uncompromised as it is primarily determined by
the wafer-fabrication process.
Mechanical stress performance is a greater consideration for a CSP package. CSPs are attached through
direct solder contact to the user’s PC board, foregoing
the inherent stress relief of a packaged product lead
frame. Solder joint contact integrity must be considered.
Information on Maxim’s qualification plan, test data, and
usage recommendations are detailed in the UCSP application note, which can be found on Maxim’s website at
www.maxim-ic.com.
