MIC59P50YV-TR

Overview

The MIC59P50YV-TR is an 8-bit parallel-input protected latched driver manufactured by Microchip Technology. It features a high-voltage capability of up to 80V and supports load voltages from 5V to 12V. The device provides a maximum output current of 500mA per channel. It is housed in a 28-LCC (J-Lead) surface-mount package, specifically PLCC28. The operational temperature range extends from -40°C to +85°C. Key electrical parameters include a bipolar Darlington driver structure for each latch.

Feature Summary

• Integrates eight CMOS data latches with dedicated bipolar Darlington transistor drivers for robust peripheral control.
• Includes comprehensive protection circuitry against transient events, over-current conditions, thermal overload, and under-voltage scenarios.
• Supports standard parallel input interfaces with common control functions for clear, strobe, and output enable operations.

Applications

• Power distribution switching systems
• General-purpose load driving applications
• Industrial peripheral interface circuits

Procurement Notes

Verify the specific package designation, as the 'YV' suffix indicates a 28-LCC form factor distinct from other series variants like SOIC or PDIP. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure supply chain sources provide valid traceability for the reel or cut-tape packaging format specified in the ordering information.

Selection Notes

Select this component when high-side or low-side driving of inductive or resistive loads requires integrated latching and fault protection. The 500mA current rating suits moderate-power peripherals. Consider the 28-pin LCC package for space-constrained surface-mount designs. Validate that the 80V breakdown voltage aligns with the target load requirements and operating environment constraints.

Part Context

This part belongs to the MIC59P50 series of latch-based peripheral drivers. It shares functional similarities with devices like the MIC5801 but offers specific high-voltage and current capabilities. The series is designed for reliable interfacing between low-voltage logic controllers and higher-voltage peripheral loads in industrial and commercial electronics.

Replacement Considerations

Direct substitutes within the same family include MIC59P50BWM and MIC59P50YN. Note that these alternatives differ in package type; BWM uses SOIC-24 while YN uses PDIP-24. Verify pinout compatibility and thermal performance before substituting across different package styles.
