Overview
The MIC4425BWM TR 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 within a supply voltage range of 4.5 V to 18 V and supports CMOS and TTL logic inputs. It functions reliably within an operating temperature range of -40°C to +85°C, featuring a quiescent supply current of 2.5 mA. This component is designed for high-speed switching applications requiring robust drive capabilities.
Feature Summary
- Dual-channel architecture providing independent control for two low-side MOSFETs
- High peak output current capability of 3 A for efficient gate charging
- Immunity to noise spiking up to 5V on the ground pin
- CMOS and TTL compatible input logic levels
Applications
- Motor control systems
- Power supply circuits
- Battery management systems
Procurement Notes
Verify the specific suffix 'TR' indicates tape-and-reel packaging versus standard tube packaging when sourcing. Confirm RoHS compliance status as some variants may differ. Ensure the supplier provides official Microchip documentation to validate the part number authenticity and manufacturing origin before procurement.
Selection Notes
Select this component for applications requiring dual low-side driving with moderate speed requirements. Consider the 35 ns transition time against faster alternatives if higher frequency operation is needed. Evaluate the SOIC-16 package size constraints against PCB layout requirements compared to other package options in the family.
Part Context
This part belongs to the MIC4423/4424/4425 family of dual 3A-peak low-side MOSFET drivers. These devices are built using a BiCMOS/DMOS process for high reliability. They are pin-compatible with previous generations like the MIC426/427/428 series but offer improved performance and noise immunity.

FAQ
What is the maximum noise immunity on the ground pin?
The device can survive up to 5V of noise spiking of either polarity on the ground pin without damage or logic upset.
Is the MIC4425BWM TR a high-side or low-side driver?
It is a low-side MOSFET driver, meaning it controls the connection between the load and ground.
