MIC58P42BWM

Overview

The MIC58P42BWM is an 8-bit serial-input protected latched driver manufactured by Microchip Technology. It operates with a high-voltage capability of up to 80V and provides a high-current output of 500mA. The device integrates eight CMOS data latches, featuring serial input and strobe interfaces. It is housed in an 18-pin SOIC package and functions as a sink-type peripheral driver.

Feature Summary

• High-voltage tolerance supporting up to 80V operation
• High-current sinking capability delivering 500mA per channel
• Integrated protection mechanisms for robust performance
• Serial input interface with strobe control for latch activation

Applications

• High-voltage peripheral driving systems
• Industrial load control applications
• Automotive electronic modules requiring high current sinks

Procurement Notes

Verify the specific suffix 'BWM' against official Microchip documentation to confirm the exact package type and temperature range. Ensure compatibility with system voltage levels not exceeding the 80V maximum rating. Cross-reference pinout configurations with the latest datasheet to prevent interface mismatches during integration.

Selection Notes

Select this component when high-voltage and high-current sinking are required for serial-controlled loads. Consider the 8-bit parallel output structure for simplified wiring in complex systems. Evaluate thermal management requirements due to the 500mA output capability. Confirm that the serial interface timing aligns with the host controller's specifications.

Part Context

This part belongs to the MIC58P42 series of serial-input latched drivers. It is designed for applications needing robust high-side or low-side switching with integrated latching functionality. The series typically includes variants with different packaging options to suit various board space constraints.

Replacement Considerations

MIC58P42BWM-TR: Same functional device in tape-and-reel packaging instead of tube.
