MIC4425BM

Overview

The MIC4425BM is a dual low-side MOSFET gate driver manufactured by Microchip Technology, housed in a 16-pin SOIC package. It delivers a peak output current of 3 A with rise and fall times of 35 ns. The device operates on a supply voltage ranging from 4.5 V to 18 V and accepts CMOS or TTL logic inputs. It functions within an operating temperature range of -40°C to +85°C and draws a working supply current of 2.5 mA.

Feature Summary

• Provides high-speed switching capability for dual low-side MOSFETs through dedicated buffer/driver channels.
• Features robust noise immunity, capable of surviving up to 5V of noise spiking on the ground pin without latch-up.
• Accepts standard CMOS and TTL logic input signals directly without requiring additional level shifting.

Applications

• Driving low-side power MOSFETs in motor control circuits
• Gate driving applications in DC-DC converters
• Power management systems requiring fast switching speeds

Procurement Notes

Verify the specific suffix 'BM' against official Microchip documentation to confirm exact temperature grade and packaging details. Confirm RoHS compliance status as some variants may differ. Check for end-of-life status or obsolescence notices before finalizing procurement plans.

Selection Notes

Select this component when a dual low-side driver with 3 A peak current and 35 ns switching speed is required. Ensure the application environment stays within the -40°C to +85°C operational range. Verify that the load capacitance and required switching frequency are compatible with the specified rise and fall times.

Part Context

This part belongs to the MIC4425 family of dual MOSFET drivers. It shares pin compatibility with related models like the MIC4423 and MIC4424. The series is designed for demanding electrical environments, offering improved reliability over predecessor families while maintaining identical footprint requirements.

Replacement Considerations

Pin-compatible alternatives include the MIC4423 and MIC4424. Verify if the specific suffix variations match the required temperature range and packaging format before substitution.
