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 open-drain output. Supply current is 1µA at +5V, operating down to +1.8V. Input range extends 200mV beyond rails. Propagation delay is 12µs at 1.8V and 31µs at 5V. Operating temperature is -40°C to +85°C.

Feature Summary

• Internal 1.236V ±1% reference
• Open-drain output stage
• Beyond-the-Rails inputs
• Crowbar-current-free switching

Applications

• 2-cell battery monitoring/management
• Ultra-low-power systems
• Mobile communications
• Notebooks and PDAs
• Sensing at ground or supply line

Procurement Notes

Verify the EB suffix indicates the specific UCSP package variant and T suffix denotes tape-and-reel packaging. Confirm RoHS compliance status for the specific ordering code. Ensure the open-drain configuration matches system logic requirements. Validate input voltage limits against application signals.

Selection Notes

Select this part when an integrated reference is required alongside low power consumption. The open-drain output supports mixed-voltage logic levels. Verify that the propagation delay meets timing constraints. Consider the UCSP footprint for space-constrained designs.

Part Context

Part of the MAX9025–MAX9028 family of nanopower comparators. Shares UCSP packaging and Beyond-the-Rails input architecture with siblings. Differentiates via internal reference inclusion and open-drain output type compared to push-pull variants.
