MIC5801BWM-TR

Overview

The MIC5801BWM-TR is a high-voltage, high-current integrated circuit manufactured by Microchip Technology. It comprises eight CMOS data latches, each driving a bipolar Darlington transistor output. The device operates at a fixed supply voltage of 5 V and supports a wide operating temperature range from -40°C to +85°C. It is housed in a 24-pin SOIC package with a width of 7.50 mm. The component utilizes Strobe, Clear, and Output Enable interfaces for latch control. It is supplied in Reel, Cut Tape, or MouseReel packaging formats.

Feature Summary

• Integrates eight independent CMOS data latches paired with high-current bipolar Darlington drivers
• Supports high-voltage operation suitable for demanding load switching applications
• Features dedicated control inputs including Strobe, Clear, and Output Enable for precise state management

Applications

• Industrial automation control systems
• High-voltage relay driver circuits
• Solenoid actuation interfaces

Procurement Notes

Verify the specific suffix and package variant against official Microchip documentation to ensure compatibility with design requirements. Confirm that the 5V supply specification aligns with system power rails. Check current availability status as distribution may be restricted. Ensure thermal management strategies account for the SOIC-24 package characteristics during operation within the specified temperature range.

Selection Notes

Select this component when eight isolated high-current outputs are required with integrated latching functionality. The fixed 5V supply requirement dictates system power architecture. Consider the SOIC-24 footprint constraints for PCB layout. Verify that the bipolar Darlington output structure meets the voltage and current demands of the intended loads without external protection components.

Part Context

This part belongs to the MIC5800/5801 family of latched drivers designed for general-purpose high-voltage switching. The MIC5801 variant specifically provides eight channels, whereas the MIC5800 offers four. These devices simplify interface design by combining logic latching with power driving capabilities in a single package, reducing component count compared to discrete solutions.
