MAX9065
Ultra-Small, nanoPower, Window Comparator
in 4 UCSP and 5 SOT23
General Description
The MAX9065 is an ultra-small, low-power, window comparator ideal for a wide variety of portable electronics
applications such as cell phones, portable media players,
and notebooks that have extremely tight board space and
power constraints. It comes in both a 4-bump UCSP™
package with a 1mm x 1mm footprint (as small as two
0402 resistors) and a 5-pin SOT23 package.
The MAX9065 features a common-mode input range of
-0.3V to +5.5V independent of supply voltage. The input
current goes to zero when the MAX9065 is powered down
(VCC = 0). Additionally, the MAX9065 features high RF
immunity.
The MAX9065 has a push-pull output and consumes only
1μA (max) supply current. The MAX9065 operates down to
1.0V over the extended -40°C to +85°C temperature range.

Detailed Description
The MAX9065 is an extremely small window comparator
designed for compact, low-current applications, featuring
a supply current of less than 1μA (max).
MAX9065 Operation
At the heart of the MAX9065 are two comparators, a
resistor-divider with a disconnect switch, a 200mV reference, digital logic circuitry, and an output stage (see the
Typical Operating Circuit).
The digital logic circuitry and the output stage together
behave like an AND gate. The gate’s inputs are the outputs of the two comparators. When either comparator’s
output is low, the output asserts low. When both comparator’s outputs are high, the output asserts high.

MAX9065A Operation
The resistor-divider provides two voltages, VUPPER and
VLOWER, for comparison with an internal 0.2V reference
voltage. When the input voltage exceeds 1.2V, VUPPER is
greater than 0.2V, causing the output to assert low.
When the input voltage falls below 0.6V, VLOWER is less
than 0.2V, causing the output also to assert low. With the
input voltage between 0.6V and 1.2V, the output asserts
high, indicating that the input voltage is within the desired
range. Table 2 summarizes the operation of the MAX9065A.
Applications
When power is applied to VCC, the n-channel FET at the
bottom of the resistor-divider is turned on. The resistordivider provides two voltages, VUPPER and VLOWER,
for comparison with an internal 0.2V reference voltage.
When the input voltage exceeds 4.2V, VUPPER is greater
than 0.2V, causing the output to assert low. When the
input voltage falls below 3.0V, VLOWER is less than 0.2V,
causing the output also to assert low. With the input voltage between 3.0V and 4.2V, the output asserts high, indicating that the input voltage is within the desired range.
Table 1 summarizes the operation of the MAX9065.
The MAX9065 is designed specifically to monitor the
voltage on a single lithium battery. Keeping the voltage
on a lithium battery within a tight range is important to
prevent damage to the battery. Specifically, ensuring that
the battery’s voltage neither exceeds 4.2V nor falls below
3.0V lengthens the lifetime of the battery and avoids any
hazardous battery conditions.
When VCC goes to 0V, the n-channel FET is turned off,
eliminating the resistor-divider as a leakage path for current.
Bypass VCC with a 0.1μF capacitor to ground.
Hysteresis
There are four trip points for hysteresis. See Figure 1.
