MIC58P42YWM-TR

Overview

The MIC58P42YWM-TR is an 8-bit serial-input protected latched driver manufactured by Microchip Technology. It features a bipolar output configuration capable of delivering up to 500mA per channel across eight outputs. The device operates within a wide supply voltage range, typically supporting 3V to 16V inputs, and includes built-in protection mechanisms such as thermal shutdown and overcurrent limiting. Packaged in an 18-SOP (Wide) format, it facilitates efficient power distribution and load control in various electronic systems requiring reliable high-current switching capabilities.

Feature Summary

• Provides eight independent high-current bipolar outputs for robust load driving
• Integrates comprehensive protection features including thermal shutdown and overcurrent limiting
• Utilizes a serial input interface for simplified data transmission and latch control

Applications

• Industrial automation control systems
• Power distribution units in embedded devices
• High-current LED lighting drivers
• Relay and solenoid actuation circuits

Procurement Notes

Verify the specific suffix 'TR' indicates tape-and-reel packaging when ordering. Confirm the operating temperature range and voltage specifications align with your system requirements. Ensure ESD handling procedures are followed due to moisture sensitivity classification. Cross-reference the datasheet revision date to ensure compatibility with existing design documentation.

Selection Notes

Select this component when an 8-channel high-current driver with serial interface is required. Consider the 18-SOP package dimensions for PCB layout constraints. Evaluate the need for bipolar outputs versus single-ended alternatives based on load type. Verify that the 500mA per channel rating meets the maximum current demands of the connected loads without exceeding thermal limits.

Part Context

This part belongs to the MIC58P series of latched drivers from Microchip Technology. It is designed for applications requiring multiple high-current outputs controlled via a simple serial interface. The series offers reliability and protection features suitable for industrial and commercial environments where stable power switching is critical.

Replacement Considerations

Check for direct substitutes within the MIC58P family or other Microchip latched drivers with similar pinouts and current ratings. Ensure any replacement maintains the 8-bit serial input functionality and 500mA output capability. Verify package compatibility if space is constrained.
