MAX9052BESA+T

Overview

The MAX9052BESA+T is a micropower, single-supply comparator integrated circuit manufactured by Analog Devices Inc./Maxim Integrated. It features dual comparators and one precision voltage reference within an 8-pin SO package. The device operates from a supply voltage range of 2.7V to 5.5V with a typical quiescent supply current of 55µA at 2.7V. The internal voltage reference provides a fixed output of 2.500V. Comparator inputs support rail-to-rail operation with a common-mode range extending 250mV beyond the supply rails. The outputs are push-pull capable of sinking and sourcing up to 8mA.

Feature Summary

• Integrates dual comparators with a precision voltage reference in a compact surface-mount package
• Features rail-to-rail input and output stages for maximum dynamic range
• 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
• Infrared (IR) receivers
• Level translators
• Digital line receivers

Procurement Notes

Verify component authenticity through authorized distribution channels. Confirm RoHS compliance status as indicated by the plus suffix. Ensure the specific B grade accuracy requirements match the application needs before procurement. Check for any obsolescence notices or lifecycle changes directly from the manufacturer.

Selection Notes

Select this component when dual comparison functions and a stable voltage reference are required in a low-power environment. The B grade offers 1% initial accuracy suitable for general-purpose applications. Consider the 8-pin SO package constraints for board layout. Evaluate if the 400ns propagation delay meets the timing requirements of the target system.

Part Context

This part belongs to the MAX9038–MAX9053 family of micropower comparators combined with precision references. The series includes variants with single or dual comparators and different reference voltages. The MAX9052 specifically pairs dual comparators with a 2.5V reference, distinguishing it from the MAX9042 which uses a 2.048V reference.

Replacement Considerations

Direct substitutes include other parts from the MAX9038–MAX9053 family such as the MAX9052AEUA or MAX9052AESA depending on the required package type.
