Description  
The IRS20955 is a high voltage, high speed MOSFET driver  
with a floating PWM input designed for Class D audio  
amplifier applications.  
Package  
Bi-directional current sensing detects over-current  
conditions during positive and negative load currents without  
any external shunt resistors. A built-in protection control  
block provides a secure protection sequence against over-  
current conditions and a programmable reset timer.  
16-Lead PDIP  
16-Lead SOIC  
The internal deadtime generation block enables accurate  
gate switching and optimum deadtime setting for better  
audio performance, such as lower THD and lower audio  
noise floor.
