Features

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.
