Chip-Scale Package
General Description
Features
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.

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 V
CC
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.
