MAX9016AEKA+T

Overview

The MAX9016AEKA+T is a dual 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 1.5µA at 25°C. The device features Beyond-the-Rails inputs extending 200mV beyond the supply rails and includes an internal 1.236V ±1% reference. It utilizes an open-drain output stage suitable for mixed-voltage systems, offering up to 50mA output short-circuit current capability.

Feature Summary

• Features Beyond-the-Rails input voltage range extending 200mV beyond the supply rails
• Includes an onboard precision 1.236V ±1% reference voltage source
• Open-drain output stage designed for mixed-voltage system compatibility
• Contains internal 4mV hysteresis to ensure clean switching without oscillation

Applications

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

Procurement Notes

Verify the specific A-grade designation ensures the inclusion of the 1.236V ±1% reference voltage. Confirm the open-drain output configuration matches the target circuit requirements compared to push-pull variants. Check the operating temperature range specifications against environmental conditions. Ensure the SOT-23 package footprint aligns with the PCB layout constraints.

Selection Notes

Select this component when low supply current consumption is critical for battery life extension. Choose the open-drain output version if interfacing with logic families requiring different voltage levels than the supply rail. Consider the integrated reference feature to reduce external component count and board space. Evaluate the Beyond-the-Rails input capability for applications where signals may exceed the positive supply voltage.

Part Context

This part belongs to the MAX9015–MAX9020 family of nanoPower comparators manufactured by Analog Devices / Maxim Integrated. The family shares common electrical characteristics such as ultra-low supply current and high precision offset voltage. Variations within the family include single or dual channel configurations and the presence or absence of an internal reference voltage.

FAQ

What is the function of the REF pin on the MAX9016AEKA+T?

The REF pin provides access to the internal 1.236V ±1% reference voltage generated by the device.

How does the open-drain output differ from push-pull outputs in this family?

The open-drain output allows the device to interface with mixed-voltage systems by pulling the output low while relying on an external pullup resistor for the high state.
