MIC4452BN

Overview

The MIC4452BN is a single-channel low-side MOSFET and IGBT gate driver manufactured by Microchip Technology. It operates within a supply voltage range of 4.5V to 18V and delivers peak output currents of 12A for both sourcing and sinking. The device features non-inverting logic inputs with defined thresholds of 0.8V (VIL) and 2.4V (VIH). It utilizes a TO-220-5 through-hole package and supports an operating temperature range from 0°C to 70°C.

Feature Summary

• Provides high-current drive capability suitable for power switching applications
• Features non-inverting input configuration for straightforward control integration
• Designed for robust operation with specified peak source and sink currents

Applications

• MOSFET gate driving in power conversion circuits
• IGBT gate driving in motor control systems
• Low-side switching applications requiring high current drive

Procurement Notes

Verify the specific suffix 'BN' against official Microchip documentation to confirm package type and temperature grade, as datasheets may list variants like VM or ZT. Confirm RoHS compliance status and lead times directly with authorized distributors, as availability varies. Ensure the TO-220-5 through-hole package matches your PCB design requirements before ordering.

Selection Notes

Select this component when a single-channel, low-side driver with high peak current is required for MOSFET or IGBT control. Compare against other MIC4452 variants based on package style (TO-220 vs SOIC) and operating temperature range. Ensure the 4.5V to 18V supply range aligns with your system's available rails and that the non-inverting logic levels are compatible with your microcontroller or logic interface.

Part Context

The MIC4452 belongs to Microchip's family of single-channel low-side gate drivers. This series is designed to provide fast switching speeds and high current drive for power transistors. Variants within the family differ primarily in packaging options such as SOIC or TO-220, and thermal performance characteristics, allowing selection based on board space and heat dissipation needs.

Replacement Considerations

MIC4452ZT is listed as a direct replacement for the discontinued MIC4452CT. Verify pinout compatibility and electrical specifications between the BN variant and potential substitutes like the VM or ZT versions to ensure seamless integration without circuit redesign.
