MAX9117EXK+T

Overview

The MAX9117EXK+T is a nanopower comparator in an SC70-5 package. It operates down to +1.6V with a supply current of 600nA. It features Beyond-the-Rails inputs extending 200mV beyond the rails, an internal 1.252V reference, and push-pull outputs capable of ±5mA drive. Propagation delay is 14µs at 5V. Operating temperature range is -40°C to +85°C.

Feature Summary

• Space-saving SC70-5 package
• Ultra-low supply current of 600nA
• Beyond-the-Rails input voltage range
• Internal 1.252V reference

Applications

• 2-cell battery monitoring/management
• Ultra-low-power systems
• Mobile communications
• Threshold detectors/discriminators
• Sensing at ground or supply line

Procurement Notes

Verify the component matches the exact part number MAX9117EXK+T. Confirm the manufacturer is Analog Devices Inc./Maxim Integrated. Ensure the package code corresponds to SC70-5. Check for lead-free status indicated by the plus sign suffix. Validate against official datasheets for electrical characteristics.

Selection Notes

Select this component for applications requiring ultra-low power consumption and operation at voltages as low as 1.6V. The integrated reference simplifies design for threshold detection. Push-pull output drives loads up to 5mA directly. Consider the SC70-5 package size for space-constrained designs.

Part Context

The MAX9117EXK+T belongs to the MAX9117–MAX9120 family of nanopower comparators. These devices are designed for battery-powered applications. The family includes variants with and without internal references and different output stages. The MAX9117 specifically combines a reference with a push-pull output.

Replacement Considerations

MIC845LYC5-TR is a confirmed substitute part number.
