MIC58P01BN

Overview

The MIC58P01BN is an 8-bit parallel-input protected latched driver manufactured by Microchip Technology. It integrates eight CMOS data latches with a bipolar power output stage, designed for high-voltage and high-current applications. The device operates with a supply voltage range of 5V to 15V and delivers up to 500mA output current in both high and low states. It features an inverting logic configuration and functions within a temperature range of -40°C to +85°C. The component is housed in a 22-pin DIP package.

Feature Summary

• Integrates eight CMOS data latches with a bipolar power driver stage for robust signal handling.
• Provides high-current output capability suitable for driving heavy loads directly.
• Features parallel input architecture for efficient multi-bit data transfer.
• Includes protection mechanisms for the latched driver outputs.

Applications

• Industrial control systems requiring high-side or low-side switching
• Relay driver circuits for automated machinery
• Solenoid actuation interfaces
• High-power LED array drivers

Procurement Notes

Verify the specific suffix BN indicates the 22-pin DIP package configuration when sourcing. Confirm RoHS compliance status as it may vary by production batch. Check for obsolescence notices or product change notifications from Microchip Technology prior to finalizing procurement decisions. Ensure the supplier provides valid traceability documentation for quality assurance purposes.

Selection Notes

Select this component when an 8-bit parallel interface is required alongside significant current drive capabilities. The bipolar output stage distinguishes it from pure CMOS alternatives, offering higher load tolerance. Consider the 22-pin DIP footprint for through-hole mounting requirements. Evaluate thermal management needs given the 500mA output capacity during continuous operation.

Part Context

This part belongs to the MIC58 series of parallel-input latched drivers. It serves as a bridge between low-voltage digital logic and high-voltage analog loads. The MIC58P01 variant represents the protected version of the driver family, enhancing reliability in noisy industrial environments compared to unprotected counterparts.

Replacement Considerations

Direct substitutes include other 8-bit parallel latched drivers from the same manufacturer family. Verify pin compatibility and electrical specifications such as voltage and current ratings before substitution. Alternative packages like SOIC-24 exist for surface mount applications but require adapter considerations.
