MAX9053BEUB-T

Overview

The MAX9053BEUB-T is a micropower, single-supply integrated circuit featuring dual comparators and a precision voltage reference. It operates from a 2.7V to 5.5V supply with quiescent current of 55µA at 2.7V and 60µA at 5V. The device provides a fixed 2.500V reference output with B-grade accuracy of ±1% initial accuracy and 100ppm/°C temperature coefficient. Comparator inputs support rail-to-rail operation with common-mode range extending 250mV beyond the rails, while outputs provide push-pull drive up to 8mA.

Feature Summary

• Integrates dual low-power comparators with a precision voltage reference in a compact package
• Features rail-to-rail input and output stages for wide signal compatibility
• Includes internal hysteresis to ensure clean switching on slow-moving signals
• Utilizes unique output stage design to minimize 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 configuration. Confirm the 'B' grade designation corresponds to the 1% initial accuracy and 100ppm/°C temperature coefficient specifications rather than the higher-precision A grade. Ensure the operating environment remains within the -40°C to +85°C temperature range defined for this variant.

Selection Notes

Select this component when dual independent comparison functions are required alongside a stable voltage reference in space-constrained designs. The 2.500V reference output is suitable for interfacing with ADCs or logic circuits requiring that specific threshold. Consider the B-grade tolerance if tighter accuracy requirements are not critical for the application.

Part Context

This part belongs to the MAX9038–MAX9043/MAX9050–MAX9053 family of micropower comparators with references. It shares architectural similarities with single-comparator variants like the MAX9051 but adds a second comparator channel. The BEUB suffix denotes the B-grade performance level and the 10-pin µMAX package type.

Replacement Considerations

Pin-for-pin compatible replacements include other members of the MAX90xx series such as the MAX9052 or MAX9043, provided the reference voltage and comparator count match the design requirements.
