MIC58P42BWM-TR

Overview

The MIC58P42BWM-TR is an 8-bit serial-input protected latched driver manufactured by Microchip Technology. It operates at a supply voltage of 5V and features high-voltage outputs up to 80V with a maximum current capability of 500mA per channel. The device utilizes Strobe and Serial interfaces for data control. It is housed in an 18-SOIC package (0.295 width, 7.50mm) designed for surface mount installation. The component supports a wide operating temperature range from -40°C to +85°C.

Feature Summary

• Provides eight independent high-current output channels capable of driving loads up to 500mA each.
• Integrates serial input functionality with strobe control for efficient data latching and management.
• Features internal protection mechanisms to safeguard the integrated circuit during operation.
• Supports high-voltage output switching capabilities suitable for demanding load applications.

Applications

• Industrial automation systems requiring high-current switching
• Motor control circuits for bipolar loads
• General-purpose power distribution networks
• Load driver applications in embedded systems

Procurement Notes

Verify the specific suffix BWM-TR against official Microchip documentation to confirm the tape-and-reel packaging configuration and RoHS compliance status. Ensure that the procurement source provides valid traceability for the 18-SOIC package variant. Cross-reference the part number with the manufacturer's latest datasheet to confirm active status and any recent product change notifications affecting specifications or availability.

Selection Notes

Select this component when an application requires multiple high-current outputs controlled via a serial interface. The 500mA per-channel rating makes it suitable for direct driving of solenoids or lamps without external transistors. Consider the 80V output limit when designing for inductive loads. The SOIC-18 package offers a compact solution for space-constrained PCB layouts compared to through-hole alternatives.

Part Context

This part belongs to the MIC58P42 series of serial-input latched drivers. It is functionally related to variants such as MIC58P42YN and MIC58P42YWM-TR, which share similar core logic but differ in package type or reel configuration. The MIC58P42BWM-TR specifically denotes the bipolar version in the 18-pin SOIC package with tape-and-reel delivery.

Replacement Considerations

Direct substitutes include MIC58P42YWM-TR and MIC58P42YN. Verify pin compatibility and thermal characteristics before substitution. Note that package dimensions may vary between SOIC and other form factors, requiring PCB footprint review.
