MIC4427BMM-TR

Overview

The MIC4427BMM-TR is a dual low-side MOSFET gate driver manufactured by Microchip Technology, housed in an 8-MSOP surface-mount package. It provides independent non-inverting outputs capable of sourcing and sinking 1.5A peak current to drive N-channel and P-channel MOSFETs. The device operates on a supply voltage range of 4.5V to 18V with logic input thresholds defined at 0.8V (VIL) and 2.4V (VIH). Typical switching performance includes a rise time of 20ns and a fall time of 29ns. It supports junction temperatures from -40°C to 150°C.

Feature Summary

• Dual independent low-side channel configuration for simultaneous control of two power switches
• High peak output current capability of 1.5A for rapid MOSFET switching transitions
• Non-inverting logic input interface compatible with standard digital control signals

Applications

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

Procurement Notes

Verify the specific suffix 'BMM' against the manufacturer's official datasheet to confirm the exact temperature grade and packaging specifications. Ensure the ordering part number matches the required tape-and-reel quantity and that the component meets RoHS3 compliance standards for the target application environment.

Selection Notes

Select this component when dual isolated low-side driving is required within a compact MSOP footprint. The 1.5A peak current rating suits moderate-power applications, while the wide operating temperature range ensures reliability in demanding thermal environments compared to commercial-grade alternatives.
