Overview
The MIC4421CM-TR is a single low-side MOSFET gate driver manufactured by Microchip Technology. It features an inverting input configuration and delivers a peak output current of 9 A for both sourcing and sinking operations. The device operates within a supply voltage range of 4.5 V to 18 V. Typical switching performance includes a rise time of 20 ns and a fall time of 24 ns, with a propagation delay of 15 ns. It is housed in an 8-SOIC package (0.154 inch width) and supports surface-mount installation. The component is designed for driving IGBTs and N-channel MOSFETs.
Feature Summary
- Provides high-current 9 A peak drive capability for rapid MOSFET and IGBT switching
- Features an inverting logic interface compatible with CMOS and TTL standards
- Utilizes a bipolar/CMOS/DMOS process for robust performance in power applications
Applications
- Driving N-channel MOSFETs in power conversion circuits
- Switching IGBT modules in motor control systems
- High-speed power stage drivers requiring fast transition times
Procurement Notes
Verify the specific suffix 'TR' indicates tape and reel packaging when ordering. Confirm that the part number corresponds to the SOIC-8 surface mount variant rather than the PDIP through-hole version. Check manufacturer documentation for RoHS compliance status and moisture sensitivity level details prior to integration into manufacturing processes.
Selection Notes
Select this component for applications requiring a single low-side driver with high peak current capability. Ensure the design accommodates the inverting input logic, where a high input signal activates the output. Verify that the PCB layout supports the 8-SOIC package dimensions and thermal requirements associated with 9 A peak currents.
Part Context
This part belongs to the MIC4421 family of MOSFET gate drivers from Microchip Technology. It is functionally similar to the TC4421 series but utilizes different semiconductor processing technology. The MIC4421CM-TR specifically denotes the surface-mount SOIC-8 package variant supplied in tape and reel format for automated assembly.
Replacement Considerations
MIC4421ZM is listed as a direct replacement option for the MIC4421CM variant. Verify pinout compatibility and electrical specifications before substitution.
