Voltage Detectors in 4-Bump (2 2)
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.

Detailed Description
Applications Information
Manual Reset Input
Interfacing to Different Logic
Voltage Components
Many µP-based products require manual reset capabil-
ity, 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 out-
puts. 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.
The MAX6408/MAX6411 have an active-low, open-
drain 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.

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 negative-
going V
transient may typically have before the
CC
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 reliabil-
ity 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.

UCSP
Mechanical stress performance is a greater considera-
tion 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 appli-
cation note, which can be found on Maxim’s website at
