MIC58P01BV

Overview

The MIC58P01BV is an 8-bit parallel-input protected latched driver manufactured by Microchip Technology. It integrates eight CMOS data latches with a bipolar output stage, designed for high-voltage and high-current applications. The device supports load voltages up to 80V and delivers continuous output currents of 500mA per channel. It operates within a supply voltage range of 3V to 15V and features comprehensive fault protection mechanisms. The component is housed in a 28-PLCC package and is rated for industrial temperature ranges.

Feature Summary

• Integrates eight independent CMOS data latches with a shared control interface for simplified parallel input driving.
• Provides robust bipolar output stages capable of sourcing and sinking high current loads up to 500mA.
• Includes built-in over-temperature and under-voltage lockout (UVLO) protection to ensure reliable operation under fault conditions.
• Supports high-voltage loads up to 80V, enabling direct interfacing with various power distribution switches.

Applications

• Driving high-side or low-side power MOSFETs and IGBTs in industrial motor control systems.
• Actuating solenoids, relays, and lamps in automotive lighting and body electronics.
• Managing power distribution sequences in telecommunications equipment and server racks.
• Controlling high-power LED arrays in commercial and industrial lighting fixtures.

Procurement Notes

Verify the specific suffix 'BV' against the manufacturer's latest datasheet to confirm pinout compatibility and thermal characteristics. Ensure that the required load voltage does not exceed the absolute maximum ratings specified in the official documentation. Confirm that the operating temperature range meets the environmental requirements of the target application, as variations may exist between production batches.

Selection Notes

Select this component when an 8-channel latch driver with high current capability and integrated protection is required. Consider the 28-PLCC package constraints for PCB layout and thermal management. Evaluate the need for external heat sinking if operating near maximum current limits. Compare against alternative series such as MIC5801 if RoHS compliance or different packaging options are mandatory for the design.

Part Context

The MIC58P01 belongs to the MIC58 family of parallel-input latched drivers from Microchip Technology. This series is designed to simplify the control of multiple power switches by combining logic latching with high-power output stages. The BV variant specifically denotes the package type and temperature rating, distinguishing it from other suffixes like YV or YWM which may offer different form factors or compliance standards.

Replacement Considerations

The MIC5801YV is listed as a direct replacement option. Verify electrical parameter equivalence and pin compatibility before substitution. Note that the MIC5801BV is marked as obsolete; therefore, the YV variant serves as the primary successor. Ensure that any substitute part meets the same voltage and current specifications for the intended load.
