MIC59P60BWM-TR

Overview

The MIC59P60BWM-TR is a serial-input latched driver featuring eight high-voltage outputs capable of handling up to 80V and 500mA. It integrates CMOS data latches with bipolar Darlington transistor drivers for each channel. The device includes common control functions for CLEAR, STROBE, and OUTPUT ENABLE. Built-in protection mechanisms encompass thermal shutdown, under-voltage lockout, over-current protection, and transient suppression. It operates within a temperature range of -40°C to 85°C and is housed in a 20-SOIC package.

Feature Summary

• Integrates eight serial-input latched channels with bipolar Darlington output drivers
• Provides comprehensive protection including thermal shutdown, under-voltage lockout, and over-current limiting
• Supports high-voltage operation up to 80V with high-current capability of 500mA per channel

Applications

• Industrial automation control systems
• Automotive peripheral driving applications
• High-voltage load switching circuits
• General-purpose latch-based driver interfaces

Procurement Notes

Verify the specific suffix TR indicates tape-and-reel packaging configuration when sourcing. Confirm the manufacturer designation as Microchip Technology or its predecessor Micrel Semiconductor depending on production date. Ensure the 20-SOIC package dimensions match your PCB footprint requirements. Check for RoHS compliance status variations across different manufacturing batches. Validate that the serial input interface matches your system's communication protocol before integration.

Selection Notes

Select this component when a serial interface is preferred over parallel inputs to reduce pin count. Choose the MIC59P60BWM-TR for applications requiring individual channel latching with high voltage tolerance. Consider the bipolar Darlington structure for higher current drive capabilities compared to pure CMOS alternatives. Evaluate the built-in transient and thermal protection features for harsh environment reliability. Ensure the 1:8 input-to-output ratio aligns with your system architecture constraints.

Part Context

This part belongs to the MIC59Pxx series of protected latched drivers from Microchip Technology. It serves as a high-voltage alternative to lower voltage logic drivers, specifically designed for industrial and automotive loads. The series typically includes both parallel (MIC59P50) and serial (MIC59P60) input variants. The BWM suffix denotes the SOIC package type, while TR indicates reel packaging for automated assembly processes.

Replacement Considerations

The MIC59P50BWM is a parallel-input variant within the same family but differs in interface type. Direct substitution requires verifying compatibility between serial and parallel control signals. No other direct cross-model replacements are confirmed in public documentation.
