IRS20124(S)PbF
Digital Audio Driver with Discrete Deadtime and Protection
Features
• 200 V high voltage ratings deliver up to 1000 W
output power in Class D audio amplifier
applications
• Integrated deadtime generation and bi-directional
over-current sensing simplify design
• Programmable compensated preset deadtime for
improved THD performances over temperature
• High noise immunity
• Shutdown function protects devices from overload
conditions
• Operates up to 1 MHz
• 3.3 V/5 V logic compatible input
• RoHS compliant
