MIC59P50YV

Overview

The MIC59P50YV is an 8-bit parallel-input protected latched driver manufactured by Microchip Technology. It operates with a high voltage rating of 80V and provides a high output current capability of 500mA per channel. The device integrates eight CMOS data latches, each driving a bipolar Darlington transistor stage. Common control functions include CLEAR, STROBE, and OUTPUT ENABLE. It supports split supply operation and includes built-in protection against transients, over-current, thermal issues, and under-voltage conditions. The component is housed in a PLCC-28 package.

Feature Summary

• Integrates eight CMOS data latches with associated bipolar Darlington drivers for high-current output switching.
• Provides comprehensive fault protection including transient suppression, fixed current limiting, thermal shutdown, and under-voltage lockout.
• Supports split supply operation to accommodate different logic and load voltage requirements.

Applications

• High-voltage peripheral interface circuits
• Industrial control system drivers
• Automotive electronic module actuation

Procurement Notes

Verify the specific suffix YV corresponds to the PLCC-28 package variant when sourcing. Confirm RoHS compliance status as some variants may differ. Ensure the supplier provides official Microchip documentation to validate the part number authenticity and revision level before procurement.

Selection Notes

Select this component for applications requiring high-side or low-side switching with significant current capacity up to 500mA. The integrated latching mechanism simplifies digital control interfaces by reducing pin count compared to non-latched drivers. Consider the 80V rating for compatibility with higher voltage loads.

Part Context

This part belongs to the MIC59P50 series of latch-based peripheral drivers. It shares functional similarities with the MIC5801 but offers enhanced protection features. The series is designed for robust industrial and automotive environments where reliable high-current switching is required.

Replacement Considerations

The MIC59P50BWM is a documented alternative within the same family, offering similar functionality in a PDSO-24 package. Verify pin-to-pin compatibility and package dimensions before substitution.
