Description
The IRS20955 is a high voltage, high speed MOSFET driver
with a floating PWM input designed for Class D audio
amplifier applications.
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.
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.
