Overview
The MAX9065EUK+T is a window comparator in a 5-pin SOT-23 package. It features fixed trigger points at 3.0V (lower) and 4.2V (upper). The device operates on a supply voltage range of 1.0V to 5.5V with a maximum supply current of 1μA. Input voltage range extends from -0.3V to +5.5V. Propagation delay is typically 25μs. It provides a push-pull output and functions within an extended temperature range of -40°C to +85°C.
Feature Summary
- Ultra-small footprint available in 4-bump UCSP or 5-pin SOT23 packages
- Ultra-low power consumption with maximum 1μA operating current
- Fixed internal threshold voltages for 3.0V lower and 4.2V upper trip points
- High RF immunity and input common-mode range extending beyond supply rails
Applications
- Cell phones
- Portable media players
- Notebook computers
- Electronic toys
- Portable medical devices
Procurement Notes
Verify the specific suffix 'EUK' corresponds to the 5-pin SOT-23 package variant rather than the 4-bump UCSP option. Confirm RoHS compliance status indicated by the '+' designation. Ensure the fixed 3.0V/4.2V thresholds align with the target battery monitoring requirements, as alternative threshold versions exist within the family.
Selection Notes
Select this component when board space is constrained and ultra-low quiescent current is critical. The fixed 3.0V to 4.2V window is optimized for single lithium-ion battery protection. Consider the MAX9065AEWS+TCNB if lower voltage thresholds around 0.6V and 1.2V are required instead. Verify that the 25μs propagation delay meets the timing constraints of the application circuit.
Part Context
The MAX9065 belongs to Maxim Integrated's nanoPower window comparator series designed for portable electronics. It integrates two comparators, a resistor-divider network, and a digital logic output stage into a single compact chip. The EUK suffix specifically denotes the lead-free, RoHS-compliant version housed in the standard 5-pin SOT-23 surface-mount package.

FAQ
What happens to the input current when the device is powered down?
When VCC is 0V, the input current drops to near zero (maximum 15nA), eliminating leakage paths through the internal resistor divider.
How does the MAX9065 indicate the input voltage is within the desired range?
The push-pull output asserts high when the input voltage is between the 3.0V lower threshold and the 4.2V upper threshold.
