MIC4425BN

Overview

The MIC4425BN is a dual low-side MOSFET gate driver manufactured by Microchip Technology, housed in an 8-pin PDIP package. It delivers a 3A peak output current with a supply voltage range of 4.5V to 18V. The device features TTL-compatible logic inputs and operates within a temperature range of -40°C to +85°C. Key electrical parameters include a typical rise/fall time of 35ns and a quiescent supply current of 2.5mA. This component is part of the MIC4425 family designed for reliable service in demanding electrical environments.

Feature Summary

• Provides high 3A-peak output current capability for driving power MOSFETs
• Features latch-up protection and withstands negative input swings down to -5V
• Offers TTL logic input compatibility independent of the supply voltage
• Ensures matched rise and fall times for consistent switching performance

Applications

• Low-side switching in motor control circuits
• Power management systems requiring fast MOSFET activation
• Industrial equipment utilizing bipolar/CMOS/DMOS driver architectures

Procurement Notes

Verify the specific suffix 'BN' against the manufacturer's current datasheet to confirm pinout and package integrity. Confirm that the component meets all required environmental operating temperatures for your application. Check for any recent product change notices or lifecycle status updates from Microchip Technology before finalizing procurement plans.

Selection Notes

Select this component when a dual low-side driver with 3A peak current is required in a through-hole DIP package. Ensure the application voltage stays within the 4.5V to 18V range. Consider the 35ns switching speed and 2.5mA quiescent current for power budget calculations. Verify that the PDIP-8 form factor fits the PCB layout constraints.

Part Context

The MIC4425BN belongs to the MIC4423/4424/4425 family of highly reliable BiCMOS/DMOS buffer/driver/MOSFET drivers. These devices are higher output current versions of the MIC4426/4427/4428 series. All three families share pin compatibility, allowing for design flexibility across different current requirements while maintaining consistent interface characteristics.
