MAX9118EXK-T

Overview

The MAX9118EXK-T is a nanopower comparator in a 5-pin SC70 package. It operates down to +1.6V with an ultra-low supply current of 600nA. The device features Beyond-the-Rails inputs extending 200mV beyond the supply rails and includes an internal 1.252V reference. It utilizes an open-drain output stage suitable for mixed-voltage systems.

Feature Summary

• Space-saving SC70 package
• Ultra-low supply current operation
• Beyond-the-Rails input voltage range
• Internal 1.252V reference
• Open-drain output configuration

Applications

• 2-Cell Battery Monitoring/Management
• Ultra-Low-Power Systems
• Mobile Communications
• Notebooks and PDAs
• Threshold Detectors/Discriminators

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type, temperature range, and lead-free status. Confirm availability through authorized distributors as stock levels fluctuate. Ensure the component matches the required pinout and electrical specifications for the target design.

Selection Notes

Select this part when an integrated reference and low power consumption are required in a minimal footprint. The open-drain output facilitates wire-OR logic and level shifting between different voltage domains. Verify that the propagation delay meets system timing requirements under expected load conditions.

Part Context

This component belongs to the MAX9117–MAX9120 family of nanopower comparators. These devices share common characteristics such as the SC70 package option and Beyond-the-Rails inputs. Variations within the family include push-pull outputs and differing supply currents based on the presence of an internal reference.

Replacement Considerations

Compatible substitutes within the same family include the MAX9117EXK-T (push-pull output) and MAX9119EXK-T (no internal reference). Ensure the replacement matches the required output stage type and reference availability.
