MAX9026EBT+T

Overview

The MAX9026EBT+T is a nanopower comparator in a 6-bump UCSP package. It features an internal 1.236V ±1% reference and draws 1µA supply current. Guaranteed operation down to +1.8V, it has Beyond-the-Rails inputs extending 200mV past the rails. The open-drain output supports mixed-voltage systems. Operating temperature range is -40°C to +85°C.

Feature Summary

• Internal 1.236V ±1% voltage reference
• Open-drain output stage for mixed-voltage logic compatibility
• Input voltage range extends 200mV beyond supply rails
• Crowbar-current-free switching minimizes power surges

Applications

• 2-cell battery monitoring and management
• Ultra-low-power portable systems
• Logic-level translation between different voltage domains
• Telemetry and remote sensing applications

Procurement Notes

Verify the EB suffix indicates the -40°C to +85°C industrial temperature grade and the T suffix denotes tape-and-reel packaging. Confirm the + designation ensures lead-free and RoHS compliance. Cross-reference the specific ordering code against official Maxim Integrated documentation to ensure correct pinout and electrical characteristics.

Selection Notes

Select this device when an integrated reference voltage is required alongside low quiescent current consumption. The open-drain output configuration is necessary for interfacing with higher voltage logic levels than the supply rail. Ensure the application benefits from the extended input common-mode range that exceeds standard supply boundaries.

Part Context

This component belongs to the MAX9025–MAX9028 family of nanopower comparators. It shares the same UCSP footprint and core architecture as the MAX9025, MAX9027, and MAX9028. Variations within the family include push-pull versus open-drain outputs and the presence or absence of an internal voltage reference.

Replacement Considerations

The MAX9025EBT+T serves as a direct functional substitute with identical specifications except for its push-pull output stage instead of open-drain. Other family members like the MAX9027EBT+T lack the internal reference and operate at lower currents.
