MAX9052BEUA-T

Overview

The MAX9052BEUA-T is a micropower, single-supply comparator integrated with a precision voltage reference. It features dual comparators and one reference in an 8-pin µMAX package. Operating from 2.7V to 5.5V, it consumes 55µA typical supply current. The device provides rail-to-rail inputs and outputs, ±3mV internal hysteresis, and a 400ns propagation delay. The reference output is fixed at 2.500V with B-grade accuracy.

Feature Summary

• Integrates dual comparators with a precision voltage reference in a compact footprint
• Features rail-to-rail input and output stages for maximum signal swing
• Includes internal hysteresis to ensure clean switching on slow-moving signals
• Utilizes a unique output stage design that minimizes supply current surges during transitions

Applications

• Precision battery management systems
• Window comparator circuits
• IR receivers
• Level translators
• Digital line receivers

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when sourcing. Confirm the 'B' grade designation aligns with the required initial accuracy and temperature coefficient specifications. Ensure the µMAX package type matches the target board layout constraints. Cross-reference the manufacturer's latest documentation for any potential obsolescence notices or lifecycle changes.

Selection Notes

Select this component for applications requiring low power consumption alongside precise voltage referencing. The dual comparator configuration allows for complex threshold monitoring within a single package. Consider the B-grade specifications if higher initial accuracy is not critical. Evaluate the 400ns propagation delay against system timing requirements before finalizing the design.

Part Context

This part belongs to the MAX9038–MAX9053 family of micropower comparators with references. It shares core architectural features with other members, such as rail-to-rail operation and low quiescent current. The specific model combines dual comparators with a 2.500V reference, distinguishing it from single-comparator variants or those with different reference voltages.

Replacement Considerations

Direct replacements include MAX9052AEUA-T for A-grade performance. Other family members like MAX9052AESA offer alternative packaging options.
