MAX9015AEKA+T

Overview

The MAX9015AEKA+T is a dual precision nanoPower comparator in an 8-pin SOT-23 package. It operates on a single supply from 1.8V to 5.5V with ultra-low supply current of 1.0µA at 1.8V and 1.1µA at 5.0V. The A-grade device includes an internal 1.236V ±1% reference. Input voltage range extends 200mV beyond the rails, and input offset voltage is guaranteed to be less than 5mV. The push-pull output stage provides rail-to-rail swing with up to 6mA drive capability.

Feature Summary

• Features Beyond-the-Rails inputs allowing operation with signals exceeding supply limits
• Includes an onboard precision voltage reference for threshold detection applications
• Push-pull output stage eliminates need for external pull-up resistors
• Internal hysteresis prevents output oscillation during slow signal transitions

Applications

• Two-cell battery monitoring and management systems
• Ultra-low power mobile communications devices
• Threshold detectors and window detectors
• Medical instruments requiring low voltage operation
• Telemetry and remote sensing systems

Procurement Notes

Verify the specific suffix 'EKA/V+' against the manufacturer's official ordering guide to confirm package type and RoHS compliance status. Confirm that the A-grade designation matches the required reference voltage tolerance. Ensure the component source is authorized to guarantee authenticity and traceability.

Selection Notes

Select this part when a dual comparator with an integrated reference is required for space-constrained designs. The push-pull output is suitable for direct logic interfacing without external components. Consider alternative grades if different reference tolerances or open-drain outputs are needed for mixed-voltage systems.

Part Context

This component belongs to the MAX9015–MAX9020 family of nanoPower comparators designed for battery-powered applications. The family offers various configurations including single and dual channels with or without internal references. All variants share the same ultra-low power architecture and small SOT-23 footprint.

Replacement Considerations

Check the MAX9017AEKA+T for identical pinout and performance with potentially different reference specifications. Verify compatibility with MAX9019EKA+T if the internal reference is not required for the application.
