Overview
The MAX9065AEWS+T is a window comparator in a 4-bump WLP package. It operates on a 1V to 5.5V supply with a maximum current of 1.35µA at 5.5V. The device features fixed trigger points: an upper threshold of 1.2V and a lower threshold of 0.6V. Propagation delay is typically 25µs. Input voltage range extends from -0.3V to +5.5V. Hysteresis is approximately 1%. Operating temperature spans -40°C to +85°C.
Feature Summary
- Ultra-small 4-bump WLP package with a 1mm x 1mm footprint
- Ultra-low power consumption with less than 1µA operating current
- Fixed internal thresholds for lithium battery monitoring (0.6V to 1.2V)
- High RF immunity and input shutdown current near zero when powered down
Applications
- Cell phones
- Portable media players
- Notebook computers
- Lithium battery voltage monitoring
Procurement Notes
Verify the specific suffix TCNB against official manufacturer documentation to confirm exact packaging, die coating, or testing variations. Ensure compatibility with the 4-bump WLP land pattern. Confirm RoHS compliance status through the datasheet revision history. Cross-reference the part number with authorized distributors to validate authenticity and traceability before procurement.
Selection Notes
Select this component for applications requiring minimal board space and ultra-low quiescent current. The fixed 0.6V to 1.2V threshold range makes it suitable for low-voltage signal monitoring. Consider the WLP package constraints during PCB layout. Verify that the 25µs propagation delay meets system timing requirements compared to faster general-purpose comparators.
Part Context
The MAX9065 series includes variants in SOT23, UCSP, and WLP packages. The AEWS variant specifically denotes the WLP package with defined electrical characteristics for the A-grade threshold version. Other series members like EBS offer different threshold voltages such as 3.0V and 4.2V. All variants share the same core nanoPower architecture and low-power design philosophy.

FAQ
What are the specific trigger points for the MAX9065AEWS+T?
The MAX9065AEWS+T has a fixed upper threshold voltage of 1.2V and a lower threshold voltage of 0.6V.
How does the device behave when VCC is removed?
When VCC goes to 0V, the internal n-channel FET turns off, eliminating the resistor-divider leakage path and reducing input current to approximately 15nA.
