MIC4427BM

Overview

The MIC4427BM is a dual low-side MOSFET driver manufactured by Microchip Technology. It features a totem-pole output stage capable of delivering a nominal peak output current of 1.5 A. The device operates within an extended temperature range, supporting minimum and maximum operating temperatures of -55 °C and +125 °C respectively. It is housed in an 8-pin DIP package with ceramic glass-sealed construction. The interface type is defined as a buffer or inverter based MOSFET driver with standard input characteristics.

Feature Summary

• Dual channel configuration for independent low-side MOSFET control
• Totem-pole output architecture providing high drive capability
• Extended industrial temperature rating for harsh environments

Applications

• Industrial motor control systems
• Power supply switching stages
• Inverter bridge circuits

Procurement Notes

Verify the specific suffix 'BM' against the official Microchip datasheet to confirm the exact temperature grade and package variant. Ensure the ordering information matches the required lead times and packaging formats listed in the manufacturer's current catalog. Cross-reference the component marking with the physical device to prevent counterfeit substitution.

Selection Notes

Select this component when a dual low-side driver with 1.5 A peak current is required. The ceramic DIP package offers robustness for high-temperature applications up to 125 °C. Consider the standard input interface compatibility with logic levels if interfacing directly with microcontrollers without additional level shifting.
