MIC58P42BV

Overview

The MIC58P42BV is an 8-bit serial-input protected latched driver designed for high-voltage and high-current applications. It integrates eight CMOS data latches with a bipolar output stage capable of delivering up to 500mA per channel. The device supports load voltages ranging from 4.5V to 15V, with internal protection against over-temperature conditions and under-voltage lockout (UVLO). It operates within a temperature range of -55°C to +125°C and utilizes a 20-pin PLCC package.

Feature Summary

• Integrates eight independent latched outputs driven by a single serial input interface
• Provides high current capability of 500mA per output channel for robust load driving
• Includes comprehensive fault protection mechanisms such as over-temperature shutdown and UVLO

Applications

• Industrial motor control systems requiring high-side or low-side switching
• Solenoid and relay driver circuits in automation equipment
• High-voltage LED array illumination drivers

Procurement Notes

Verify the specific suffix 'BV' indicates the 20-PLCC package variant when sourcing. Confirm that the manufacturer documentation specifies the operating temperature range extends to -55°C, which exceeds standard industrial limits. Ensure the design accounts for the 500mA peak current rating and thermal dissipation requirements associated with the PLCC footprint.

Selection Notes

Select this component for applications requiring high voltage tolerance and significant current drive per channel. The serial input architecture reduces pin count compared to parallel interfaces. Consider the extended temperature range for harsh environments. Evaluate thermal management needs due to the high current output capability and the specific package thermal characteristics.

Part Context

This part belongs to the MIC58P42 series of serial-input latched drivers. It is functionally similar to other variants like MIC58P42YN but differs in packaging. The series is characterized by its ability to handle high voltages and currents while maintaining simple serial control logic for efficient system integration.

Replacement Considerations

MIC58P42BV-TR is the tape-and-reel version of the same functional device. Cross-reference with MIC5891YWM for similar latch functionality, though pinouts and specifications may differ.
