MIC4427YMM

Overview

The MIC4427YMM is a dual low-side MOSFET gate driver manufactured by Microchip Technology. It operates within a supply voltage range of 4.5 V to 18 V and delivers a peak output current of 1.5 A. The device features non-inverting logic compatible with CMOS and TTL inputs. Electrical performance includes a typical rise time of 20 ns and a fall time of 29 ns, with maximum on/off delays of 40 ns. It is housed in an 8-MSOP surface-mount package and supports an operating temperature range from -40°C to +85°C.

Feature Summary

• Dual-channel architecture providing independent control for two low-side MOSFETs
• High-speed switching capability with nanosecond-level propagation delays
• Robust drive strength supporting 1.5 A peak source and sink currents
• Direct interface compatibility with standard digital logic families

Applications

• Synchronous rectification circuits in DC-DC converters
• Motor control systems requiring low-side switching
• Power supply topologies utilizing external N-channel MOSFETs

Procurement Notes

Verify the specific suffix 'YMM' confirms the 8-MSOP package and industrial temperature grade. Ensure procurement channels provide original manufacturer documentation to validate RoHS compliance and authenticity. Cross-reference the full part number against official Microchip databases to confirm availability status and lead times prior to ordering.

Selection Notes

Select this component when designing circuits requiring dual independent low-side driving without inversion. It is suitable for applications needing fast switching speeds and moderate current drive capabilities. Consider the MSOP package constraints for PCB layout if space is limited. Verify input voltage levels match the system's logic family requirements.

Part Context

This device belongs to the MIC4427 series of dual MOSFET drivers. It shares functional similarities with the MIC4426 but differs in logic configuration, offering non-inverting outputs instead of inverting ones. The series is designed for efficient power management in compact electronic systems.

Replacement Considerations

The MIC4427YM serves as a tube-packaged alternative with identical electrical specifications. The MIC4427ZM is available for commercial temperature range applications. Verify pinout and thermal characteristics before substituting.
