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.
