MIC4101BM

Overview

The MIC4101BM is a half-bridge MOSFET gate driver IC manufactured by Microchip Technology. It operates with a supply voltage range of 5V to 20V and supports input logic levels compatible with TTL standards. The device features non-inverting output configuration and is housed in an 8-SOIC package. Designed for driving N-channel power MOSFETs, it provides robust performance for high-side and low-side switching applications within the 100V half-bridge topology.

Feature Summary

• Non-inverting half-bridge gate driver architecture
• TTL-compatible input logic interface
• Integrated bootstrap diode support for high-side drive

Applications

• Motor control systems
• Power supply inverters
• DC-DC converter stages

Procurement Notes

Verify the manufacturer marking as Micrel or Microchip Technology, as the component originated from Micrel before acquisition. Confirm the package type is 8-SOIC and check for RoHS compliance status. Note that availability may vary as some distributors list this part as discontinued; ensure the source provides valid datasheets matching the specific suffix BM.

Selection Notes

Select this component when a non-inverting half-bridge driver is required for N-channel MOSFETs operating up to 100V. Ensure the application requires TTL-compatible inputs and fits within the 5V to 20V supply voltage range. Consider the 8-SOIC package constraints for thermal management and PCB layout space compared to other driver packages.

Part Context

This part belongs to the MIC4101 series of half-bridge drivers. It is functionally related to variants such as the MIC4101BM-TR, which differs primarily in packaging format (tube vs. tape and reel). The series is designed for efficient switching of power MOSFETs in bridge configurations.

Replacement Considerations

Check for MIC4101BM-TR if reel packaging is preferred. Verify compatibility with other half-bridge drivers from the same family, ensuring pinout and electrical specifications match exactly before substitution.
