Description
The IRS20954 is a high voltage, high speed MOSFET driver with floating PWM input, specially designed for Class D audio amplifier applications. The bi-directional current sensing requires no external shunt resistors. It can capture over-current conditions at either positive or negative load current direction. A built-in control block provides secure protection sequence against over-current conditions, including a programmable reset timer. The internal deadtime generation block provides accurate gate switch timing and enables optimum deadtime settings for better audio performances, such as THD and audio noise floor.
- Floating PWM input enables easy half bridge implementation
- Integrated programmable bi-directional over-current protection with self-reset function
- Programmable compensated preset deadtime for improved THD performances
- High noise immunity
- ±100 V high voltage ratings deliver up to 500 W output power
- 3.3 V / 5 V logic compatible input
- Operates up to 800 kHz
- RoHS compliant
