19-4224; Rev 1; 10/08 EVALUATION KIT AVAILABLE Ultra-Small, Low-Power, Window Comparator in 4 UCSP and 5 SOT23 Features 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. ♦ Tiny 1mm x 1mm 4-Bump UCSP Footprint = Two 0402 Resistors Also Available in 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. ♦ 1.0V to 5.5V VCC Range Applications Cell Phones ♦ Ultra-Low Power Operating Current 1µA (max) ♦ -0.3V to +5.5V Input Voltage Range ♦ 3.0V and 4.2V Trigger Points ♦ -40°C to +85°C Extended Temperature Range Ordering Information PART PIN-PACKAGE TOP MARK MAX9065EBS+ 4 UCSP AGC MAX9065EUK+ 5 SOT23 AFFL Note: All devices are specified over the extended -40°C to +85°C operating temperature range.

Ground Window Comparator Input Push-Pull Output 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). Table 1. MAX9065 Operation INPUT VOLTAGE OUTPUT VIN > 4.2V Low 3.0V < VIN < 4.2V High VIN < 3.0V Low 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. When VCC goes to 0V, the n-channel FET is turned off, eliminating the resistor-divider as a leakage path for current. Operation Applications 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. When power is applied to VCC, the n-channel FET at the bottom of the resistor-divider is turned on. The resistor-divider provides two voltages, V UPPER 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 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. Hysteresis There are four trip points for hysteresis. See Figure 1. Power-Supply Considerations Bypass VCC with a 0.1µF capacitor to ground.
