MAX9017AEKA+T

Overview

The MAX9017AEKA+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 1.8V and 1.4µA at 5V. The device features a push-pull output stage capable of driving loads up to ±6mA. It includes an internal 1.236V reference with ±1% accuracy and built-in 4mV hysteresis. Input offset voltage is guaranteed to be less than 5mV, and the input common-mode range extends 200mV beyond the rails.

Feature Summary

• Features Beyond-the-Rails inputs allowing operation with signals extending 200mV beyond the 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

• 2-cell battery monitoring and management systems
• Ultra-low power portable devices such as mobile communications equipment
• Threshold detectors and discriminators
• Window detectors and sensing applications at ground or supply lines

Procurement Notes

Verify the specific suffix '+T' indicates tape-and-reel packaging when ordering. Confirm that the 'A' grade designation corresponds to the required 1.236V ±1% reference accuracy. Ensure the SOT-23-8 footprint matches the design layout. Check for AEC-Q100 Grade 3 qualification if automotive compliance is mandatory for the application environment.

Selection Notes

Select this component for designs requiring ultra-low quiescent current in space-constrained environments. The dual configuration reduces board space compared to single comparators. The integrated reference eliminates the need for external voltage sources. Choose this part over open-drain versions when active sourcing and sinking capabilities are necessary for load driving.

Part Context

This device belongs to the MAX9015–MAX9020 family of nanoPower comparators manufactured by Analog Devices / Maxim Integrated. The family offers various configurations including single and dual channels with or without internal references. The MAX9017 specifically denotes the dual channel variant with a push-pull output and A-grade reference.

Replacement Considerations

The MAX9017AEKA-V+T is a qualified automotive version within the same series. Other family members like MAX9015 or MAX9019 offer similar electrical characteristics but may differ in output stage type or reference inclusion.
