Overview
The MIC4424YM is a dual low-side MOSFET gate driver manufactured by Microchip Technology. It features two independent non-inverting drivers with a peak output current of 3 A. The device operates within a supply voltage range of 4.5 V to 18 V and supports TTL logic inputs. Key timing parameters include a rise time of 28 ns, a fall time of 32 ns, and maximum on/off delays of 33 ns. It functions in temperatures from -40°C to +85°C and is housed in an 8-SOIC package.
Feature Summary
- Dual independent low-side driver configuration for simultaneous control
- High peak output current capability of 3 A for rapid switching
- Non-inverting logic input compatibility with TTL standards
- Fast propagation delay characteristics for high-frequency applications
Applications
- Low-side MOSFET switching in power conversion circuits
- Gate drive stages in isolated power supplies
- Motor control systems requiring dual channel drive
- Industrial power management IC interfaces
Procurement Notes
Verify the specific suffix 'YM' corresponds to the SOIC-8 tube packaging variant when ordering. Confirm RoHS compliance status via the manufacturer's latest documentation. Ensure the operating temperature range meets system requirements as industrial grades may differ. Cross-reference datasheet revision dates to validate electrical specifications against current production batches.
Selection Notes
Select this component for designs requiring dual-channel low-side driving with moderate speed. The 3 A peak current suits standard power MOSFETs. Verify input voltage levels align with the TTL threshold requirements. Consider thermal dissipation limits given the 960 mW power dissipation rating in the SOIC-8 package. Evaluate if the non-inverting configuration matches the control logic polarity.
Part Context
The MIC4424YM belongs to the MIC442x series of gate drivers from Microchip Technology, formerly Micrel. This series focuses on providing robust, high-current drive capabilities for power electronics. The YM suffix specifically denotes the surface-mount SOIC-8 package variant intended for automated assembly processes in commercial and industrial equipment manufacturing.
Replacement Considerations
Check for MIC4424YN which shares identical electrical specifications but differs in packaging format. Verify pinout compatibility before substitution. Review updated datasheets for any parameter shifts due to manufacturing site changes or material updates.
