IRS20957S
Description
The IRS20957S 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 dead-time generation block enables accurate gate switching and optimum dead-time setting
for better audio performance, such as lower THD and lower audio noise floor.
