International Rectifier has introduced the world's first 1000V radiation-hardened power MOSFET.
Also, these features allow audio designers to simplify circuits and minimise component count for Class D audio amplifiers in home theatre entertainment systems, audio-video receivers and automotive sound systems.
The internal, selectable dead-time generation circuit is thermally compensated for stability, and is immune to noise and supply voltage fluctuations to help improve total harmonic distortion, or THD.
The IRS20124SPbF has built-in bidirectional current sensing and combines with an integrated shutdown function to protect the output MOSFETs when an overcurrent condition occurs, such as a short-circuited speaker wire.
The new IRS20124SPbF Class D audio high voltage control IC is available immediately.
The device is lead-free and RoHS-compliant.
