MIC842LBC5 TR

Comparators Overview

The MIC842LBC5-TR is a single-channel analog comparator from Microchip Technology, housed in an SC-70-5 package. It features a push-pull output capable of sourcing or sinking 20 mA. The device operates on a single supply voltage ranging from 1.5 V to 5.5 V with a typical quiescent current of 3 µA. It includes an internal voltage reference and offers a propagation delay of 12 µs with 20 mV hysteresis. The component functions reliably within an operating temperature range of -40°C to +85°C.

Comparators Feature Summary

• Integrates an on-chip precision voltage reference for stable threshold detection without external components.
• Provides push-pull output stage capability to drive loads directly with 20 mA sink/source current.
• Designed for low-power applications with a quiescent current specification of 3 µA.

Comparators Applications

• Voltage monitoring systems requiring precise threshold detection.
• Battery-powered devices utilizing the low quiescent current profile.
• General-purpose signal comparison in industrial control circuits.

Comparators Procurement Notes

Verify the specific suffix and tape-and-reel configuration against the manufacturer's latest datasheet before ordering. Confirm that the SC-70-5 package dimensions match your PCB footprint requirements. Ensure the operating temperature range meets your environmental specifications. Cross-reference the part number with official Microchip documentation to avoid confusion with similar variants in the MIC842 family.

Comparators Selection Notes

Select this component when a push-pull output is required for direct load driving, as opposed to open-drain alternatives in the same series. Consider the 12 µs propagation delay for timing-sensitive applications. The integrated reference simplifies design by reducing external component count compared to comparators lacking internal references. Evaluate the 3 µA quiescent current against system power budgets for battery-operated designs.

Comparators Part Context

This part belongs to the MIC842 family of micropower, precision voltage comparators manufactured by Microchip Technology. The family shares core architectural features but varies in output type, package style, and specific electrical characteristics. The MIC842LBC5-TR specifically denotes the SC-70-5 package variant with push-pull output and tape-and-reel packaging.

Comparators Replacement Considerations

Check the MIC842LYC5-TR for identical performance with potentially different manufacturing lot codes. The MIC842NYC5-TR offers similar functionality but features an open-drain output instead of push-pull. Verify pin compatibility and electrical parameters before substituting any alternative part numbers.
