MIC58P42YN

Overview

The MIC58P42YN is an 8-bit serial-input protected latched driver manufactured by Microchip Technology. It features a bipolar output configuration capable of sourcing and sinking up to 500mA per channel, housed in an 18-pin DIP package. The device operates within a supply voltage range of 4.5V to 12V and supports a wide operating temperature range from -40°C to +85°C. Designed for robust industrial applications, it includes built-in protection mechanisms to ensure reliable performance under varying load conditions.

Feature Summary

• Provides high-current bipolar drive capability suitable for direct load control
• Integrates serial input interface to minimize pin count and simplify system design
• Includes internal protection features to enhance circuit reliability and longevity

Applications

• Industrial automation control systems requiring high-side or low-side switching
• Solenoid and relay driving circuits in machinery
• Motor control interfaces for small DC motors

Procurement Notes

Verify the specific suffix 'YN' corresponds to the 18-DIP tube packaging variant when ordering. Confirm that the required current rating of 500mA aligns with your application's thermal management capabilities. Ensure the supply voltage does not exceed the maximum limit of 12V to prevent device damage. Cross-reference the datasheet for exact pinout configurations to avoid PCB layout errors during integration.

Selection Notes

Select this component when a single IC needs to drive multiple high-current loads via a serial interface. It is appropriate for designs where space constraints favor fewer pins compared to parallel drivers. Consider the thermal dissipation requirements of the DIP package if driving multiple channels simultaneously at full load. Verify compatibility with the host microcontroller's serial protocol specifications before finalizing the design.

Part Context

This part belongs to the MIC58P42 series of latched drivers, designed for robust industrial environments. It complements other logic ICs by providing power stage functionality with integrated protection. The series offers various package options, with the YN suffix denoting the through-hole DIP format. It serves as a bridge between low-power digital logic and higher-power analog loads.

Replacement Considerations

Direct substitutes may include other 8-bit serial latched drivers from Microchip or compatible manufacturers offering similar 500mA bipolar outputs. Verify pin-to-pin compatibility and electrical characteristics such as voltage ranges and protection features. Alternative packages like SOIC-18 (e.g., MIC58P42YWM) may require PCB redesign but offer equivalent functionality.
