SI8244BB-D-IS1R
Overview
The SI8244BB-D-IS1R is a high-performance isolated Class D audio driver designed to provide high-side and low-side gate drive for power stages. It features an integrated PWM interface and provides up to 4A of peak output current, making it suitable for driving large MOSFETs or IGBTs in power conversion and audio amplification applications. The device operates across a wide temperature range of -40C to 125C and supports a supply voltage range of 4.5V to 5.5V for the primary side.
Why Choose This Part
This driver offers superior noise immunity and high peak output current of 4A to ensure fast switching and reduced thermal losses. Its integrated isolation technology replaces discrete optocouplers, providing better timing accuracy and long-term reliability in compact SOIC-16 packaging.
Applications
Key Specifications
Getting Started
To evaluate this part, design a PCB layout that minimizes the loop area between the driver outputs and the MOSFET gates. Use high-quality bypass capacitors on the VDD pins and ensure the primary and secondary grounds are appropriately isolated according to your system safety requirements.
