MIC59P50YWM

Overview

The MIC59P50YWM is an 8-bit parallel-input protected latched driver manufactured by Microchip Technology. It features a SOIC-24 package and operates with a supply voltage range of 5 V to 15 V. The device provides high-current output capabilities, supporting both low-level and high-level sink currents of up to 500 mA. It is designed for high-voltage applications, handling loads up to 80 V. The component includes built-in protection against transient events, overcurrent conditions, thermal issues, and undervoltage situations. It functions as a latch-based peripheral driver with standard input characteristics.

Feature Summary

• Integrates eight CMOS data latches with bipolar Darlington transistor drivers for each channel.
• Provides comprehensive internal protection mechanisms including transient, overcurrent, thermal, and undervoltage safeguards.
• Supports split supply operation for flexible system integration.

Applications

• High-voltage peripheral driving in industrial control systems
• Parallel interface circuits requiring high current sinking capability
• Automotive electronic modules needing robust latch-based drivers

Procurement Notes

Verify the specific suffix 'YWM' corresponds to the SOIC-24 surface-mount package variant when sourcing. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor declarations, as regulatory adherence varies by production batch. Ensure that the procurement source provides valid traceability for the Microchip Technology part number to guarantee authenticity and technical specification accuracy.

Selection Notes

Select this component for designs requiring parallel data latching with high-current output stages. The 500 mA per-channel capability suits direct driving of relays or solenoids without external transistors. Consider the 80 V voltage rating for high-side or low-side switching applications. Verify that the 5 V to 15 V logic supply aligns with the system's available power rails and that the SOIC-24 footprint fits the PCB layout constraints.

Part Context

This device belongs to the MIC59P50 series of latch-based peripheral drivers. It shares functional similarities with the MIC5801 but offers enhanced protection circuitry. The series is designed for interfacing low-voltage digital logic with high-voltage, high-current analog loads, providing a compact solution for embedded control applications requiring isolated or protected output channels.

Replacement Considerations

The MIC59P50BWM is a documented substitute part number within the same product family, offering similar latch-based driver functionality.
