MIC59P50BWM-TR

Overview

The MIC59P50BWM-TR is an 8-bit parallel-input latched driver featuring a high-voltage rating of 80V and a continuous output current capability of 500mA. It integrates eight 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 limiting, and transient suppression. It operates within a maximum junction temperature of 85°C and utilizes a 24-pin SOIC package.

Feature Summary

• Integrates eight independent channels with dedicated CMOS latches and bipolar Darlington drivers
• Provides comprehensive internal protection against thermal overload, under-voltage conditions, and over-current events
• Supports split supply operation for flexible system integration

Applications

• High-voltage peripheral interface circuits
• Industrial load driving applications
• Automotive electronic control modules

Procurement Notes

Verify the specific suffix 'BWM' against the manufacturer's current product line status, as distributor listings indicate potential obsolescence or replacement by RoHS-compliant variants such as the MIC59P50YWM. Confirm that the tape-and-reel packaging format aligns with automated assembly requirements. Ensure the component meets all environmental compliance standards required for the target application before finalizing procurement orders.

Selection Notes

Select this component when designing systems requiring high-side or low-side switching capabilities with integrated logic latching. The 80V rating suits automotive and industrial loads exceeding standard voltage levels. Consider the 500mA per-channel current limit for direct drive applications without external amplification. Evaluate the need for parallel input interfaces versus serial alternatives based on board space and pin count constraints.

Part Context

This part belongs to the MIC59P50 family of latch-based peripheral drivers manufactured by Microchip Technology. It serves as a bridge between low-voltage digital logic and high-voltage analog loads. The series offers robust protection features essential for harsh environments. The BWM variant specifically denotes the non-RoHS compliant version in the 24-SOIC package, distinguishing it from newer environmental standards.

Replacement Considerations

Distributor records identify the MIC59P50YWM as a confirmed replacement for the MIC59P50BWM. The YWM variant maintains similar functional characteristics while adhering to RoHS compliance standards. Verify pin compatibility and electrical specifications before substituting to ensure seamless integration into existing designs.
