MAX9015AEKA-T

Overview

The MAX9015AEKA-T is a dual precision nanoPower comparator in an 8-pin SOT-23 package. It operates on a supply voltage range of 1.8V to 5.5V with a typical supply current of 1.2µA at 5V. The device features Beyond-the-Rails inputs extending 200mV beyond the supply rails, an internal 1.236V ±1% reference, and a maximum input offset voltage of 5mV. It includes 4mV internal hysteresis and utilizes a push-pull output stage capable of driving loads up to 6mA.

Feature Summary

• Features Beyond-the-Rails inputs allowing operation 200mV beyond supply rails
• Includes an onboard 1.236V ±1% precision reference for A-grade packages
• Push-pull output stage provides rail-to-rail swing with high drive capability
• Internal 4mV hysteresis ensures clean switching without external components

Applications

• Two-cell battery monitoring and management systems
• Ultra-low power portable electronic devices
• Threshold detectors and discriminators
• Window detectors for voltage supervision
• Medical instruments and telemetry systems

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging configuration. Confirm the 'A' grade designation corresponds to the 1.236V ±1% reference requirement. Ensure the ordering code matches the exact pinout and electrical specifications required for the target design.

Selection Notes

Select this component when ultra-low quiescent current is critical for battery life. The integrated reference eliminates the need for external voltage sources. Choose the push-pull output version if direct logic interfacing or higher drive currents are necessary compared to open-drain alternatives.

Part Context

This part belongs to the MAX9015–MAX9020 family of nanoPower comparators designed for space-constrained applications. The family offers various configurations including single and dual channels with or without internal references. These devices are optimized for low-voltage operation and minimal power consumption in portable electronics.

Replacement Considerations

Check for compatible parts within the MAX9015–MAX9020 series that match the required channel count and reference accuracy. Verify equivalent performance in terms of supply current, input offset voltage, and package dimensions before substitution.
