Overview
The MIC4428CM is a dual low-side MOSFET gate driver manufactured by Microchip Technology. It features two independent drivers capable of sourcing and sinking 1.5 A peak output current. The device operates within a supply voltage range of 4.5 V to 18 V. It supports both inverting and non-inverting input configurations. Typical rise and fall times are 20 ns and 29 ns, respectively. The component is housed in an 8-SOIC package and is rated for operation from -40°C to +150°C junction temperature.
Feature Summary
- Dual independent channel architecture for driving multiple low-side MOSFETs
- High peak output current capability of 1.5 A for rapid switching
- Flexible logic interface supporting inverting and non-inverting inputs
Applications
- Low-side power switching in motor control systems
- DC-DC converter output stage driving
- General-purpose high-speed MOSFET gate drive applications
Procurement Notes
Verify the specific suffix 'CM' against the manufacturer's official datasheet to confirm the SOIC-8 package and commercial grade temperature rating. Ensure the ordering part number matches the exact pinout and electrical specifications required for the target circuit design before procurement.
Selection Notes
Select this component when dual independent low-side drive is required with moderate speed and high current capability. It is suitable for applications where inverting and non-inverting signals are needed simultaneously. Consider thermal management requirements given the 1.5 A peak current and SOIC-8 package constraints.
Part Context
The MIC4428CM belongs to the MIC442x family of dual low-side MOSFET drivers. This series provides robust gate drive solutions for power electronics. The 'CM' designation typically indicates the 8-SOIC package variant. It serves as a cost-effective solution for driving N-channel and P-channel MOSFETs in various industrial and consumer applications.
Replacement Considerations
Check for direct substitutes such as the MIC4428YM or MIC4428MM if different packaging is required. Verify that any replacement maintains the 1.5 A peak current and 4.5V-18V supply range compatibility.
