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 overcurrent 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.
