MAX9019EKA+TG0N

Overview

The MAX9019EKA+TG0N is a dual nanoPower comparator in an 8-pin SOT23 package. It operates down to 1.8V with an ultra-low supply current of 0.85µA at 1.8V and 1.7µA at 5.0V. The device features Beyond-the-Rails inputs extending 200mV beyond the supply rails, a maximum input offset voltage of 5mV, and internal 4mV hysteresis. It utilizes a CMOS push-pull output stage capable of ±6mA drive.

Feature Summary

• Ultra-low power consumption suitable for battery monitoring
• Beyond-the-Rails input capability for ground or supply line sensing
• Push-pull output stage with high drive strength
• Internal hysteresis prevents oscillation

Applications

• 2-cell battery monitoring and management
• Threshold detectors and discriminators
• Window detectors
• Sensing at ground or supply lines

Procurement Notes

Verify the specific suffix 'G0N' against official manufacturer documentation to confirm tape-and-reel packaging details. Ensure the component matches the standard MAX9019 electrical specifications and pinout configuration before integration into designs.

Selection Notes

Select this part for applications requiring low-voltage operation and minimal quiescent current. The push-pull output eliminates the need for external pull-up resistors compared to open-drain variants. Verify that the required input common-mode range extends beyond the supply rails if necessary.

Part Context

This component belongs to the MAX9015–MAX9020 family of nanoPower comparators. These devices are designed for space-constrained applications using the SOT23 package. The family includes single and dual versions with varying output stages and reference options.

Replacement Considerations

Direct replacements within the same family include the MAX9020, which shares the dual configuration but features an open-drain output instead of push-pull. Other family members like the MAX9017 offer similar performance with an integrated reference.
