The Si824x family from Skyworks Solutions, Inc. includes high-side/low-side isolated drivers specifically designed for high-power (>30 W) audio applications, providing versions with peak output currents of 0.5 A (Si8241) and 4.0 A (Si8244). These drivers operate with a maximum supply voltage of 24 V and feature an innovative isolation technology that offers up to 2500 V input-to-output isolation and up to 1500 Vrms output-to-output isolation, enabling level translations of signals without additional external circuits. Key features include a high-precision linear programmable dead-time generator ranging from 0.4 ns to 1 us, robust transient immunity of over 45 kV/us, a wide operational temperature range from -40 to +125 °C, and overlap protection to prevent shoot-through current damage. The Si824x components are RoHS-compliant and come in a 16-pin narrow body SOIC package, making them suitable for integration in space-constrained designs. These characteristics make the Si824x family ideal for use in Class D audio amplifiers and other high-side/low-side driving applications where high noise immunity and precise timing control are critical.

The AON7292 from Alpha & Omega Semiconductor is a high-performance, 100V N-Channel MOSFET utilizing the latest Trench Power AlphaMOS (aMOS MV) technology. This component is optimized for fast-switching applications and features very low RDS(ON) values, with <24mΩ at VGS=10V and <32mΩ at VGS=4.5V, making it ideal for synchronous rectification in DC/DC and AC/DC converters, as well as isolated DC/DC converters in telecom and industrial applications. The AON7292 is housed in a compact DFN 3.3×3.3 package and complies with RoHS and Halogen-Free standards. Key specifications include a continuous drain current of 23A at Tc=25°C, a pulsed drain current of 45A, and a maximum power dissipation of 28W at Tc=25°C. The component also boasts low gate charge characteristics, with a total gate charge of 17nC at VGS=10V, ensuring efficient operation in high-speed switching environments. Additionally, it has been rigorously tested for Unclamped Inductive Switching (UIS) and gate resistance, ensuring reliability and performance in demanding applications.
