MIC59P50YWM-TR

Overview

The MIC59P50YWM-TR is an 8-bit parallel-input protected latched driver manufactured by Microchip Technology. It integrates eight CMOS data latches, each paired with a bipolar Darlington transistor driver, and common control circuitry for CLEAR, STROBE, and OUTPUT ENABLE functions. The device supports high-voltage operation up to 80V and delivers high-current drive capability of 500mA per channel. It is housed in a 24-pin SOIC package.

Feature Summary

• Integrates eight independent channels with individual CMOS data latches and bipolar Darlington drivers
• Includes built-in protection mechanisms such as thermal shutdown, under-voltage lockout, over-current, and transient protection
• Features common control inputs for CLEAR, STROBE, and OUTPUT ENABLE functions across all channels

Applications

• High-voltage peripheral driving in industrial automation systems
• Load switching and power distribution in automotive electronics
• Driving solenoids, relays, or lamps in embedded control applications

Procurement Notes

Verify the component authenticity through authorized Microchip distributors or certified suppliers. Confirm the part number suffix matches the specified reel or cut tape packaging variant. Ensure compliance with RoHS standards if required by your manufacturing process. Cross-reference the datasheet revision date to ensure compatibility with your design specifications. Request batch-specific documentation for quality assurance records.

Selection Notes

Select this component when designing circuits requiring isolated, latched control of multiple high-voltage loads. Consider the 80V voltage rating and 500mA current capacity per channel against load requirements. Evaluate the need for thermal management given the bipolar driver structure. Compare pin count and package size constraints against available PCB space. Verify logic level compatibility for the parallel input interface.

Part Context

This part belongs to Microchip's family of latch-based peripheral drivers, designed for robust control of external loads. It shares functional similarities with other devices like the MIC5801 but offers higher voltage and current ratings. The series targets applications needing reliable, protected switching without complex microcontroller overhead for each channel.

Replacement Considerations

Check for direct substitutes within the MIC59P50 series or compatible drivers from Microchip. Verify pin-out compatibility and electrical parameters before substitution. Ensure any alternative part meets the same voltage, current, and protection specifications.
