MAX9017AEKA/V+T

Overview

The MAX9017AEKA/V+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 2.3µA at 5V. The device features a push-pull output stage capable of rail-to-rail swing with up to 6mA drive. It includes an internal 1.236V ±1% reference, input offset voltage max of 5mV, and 4mV internal hysteresis. Qualified under AEC-Q100 Grade 3 for automotive use.

Feature Summary

• Features Beyond-the-Rails inputs extending 200mV beyond the supply rails.
• Includes an onboard 1.236V ±1% precision voltage reference.
• 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
• Ultra-low power systems
• Mobile communications devices
• Threshold detectors and discriminators
• Window detectors

Procurement Notes

Verify the specific suffix /V indicates AEC-Q100 Grade 3 qualification for automotive applications. Confirm the 'A' grade designation corresponds to the 1.236V ±1% reference tolerance rather than the B-grade 1.24V ±1.75% variant. Ensure the ordering code matches the required SOT-23-8 packaging format.

Selection Notes

Select this component when low supply current is critical alongside the need for an integrated voltage reference. The push-pull output is suitable for direct logic interfacing, whereas open-drain versions are required for mixed-voltage wire-OR configurations. Verify that the 5mV maximum input offset voltage meets the precision requirements of the sensing application.

Part Context

This part belongs to the MAX9015–MAX9020 family of nanoPower comparators designed for space-saving SOT-23 packages. The MAX9017 specifically denotes the dual-channel configuration with a push-pull output stage. It shares the same core architecture as single-channel variants but offers two independent comparators within the compact footprint.

Replacement Considerations

Consult the manufacturer datasheet for equivalent single-channel parts like the MAX9015 or MAX9019 if only one comparator channel is needed. For open-drain output requirements, consider the MAX9018. No direct cross-manufacturer substitutes are confirmed in the provided documentation.
