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
VCC supply 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 VCC is below VTH). The MAX6407/
MAX6410 have an active-high push-pull output (OUT
is logic high when VCC is below VTH). All parts are
guaranteed to be in the correct output logic state for
VCC down 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
).

The MAX6406–MAX6411 are available in factory-set VCC
detector thresholds from 2.20V to 4.63V, in approximately 0.1V
increments. Choose the desired threshold suffix from Table 1
and insert it in the blank space following “S”. There are 21
standard versions with a required order increment of 2500
pieces. Sample stock is generally held on the standard ver-
sions only (Table1). Required order increment is 10,000 pieces
for nonstandard versions (Table 2). Contact factory for avail-
ability. All devices available in tape-and-reel only.
UCSP reliability is integrally linked to the user’s assembly
methods, circuit board material, and environment. Refer to the
UCSP Reliability Notice in the UCSP Reliability section of this
data sheet for more information.
