IRS20957SPBF General Description
The IRS20957S is a high voltage, high speed MOSFET driver with a floating PWM input designed for Class D audio amplifier applications. It features a bi-directional current sensing to detect 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.
Features
- · Floating PWM input enables easy half -bridge implementation
- · Programmable bidirectional over-current protection with self -reset function
- · Programmable preset deadtime for improved THD performances
- · High noise immunity
- · ±100 V ratings deliver upto 500 W in output power
- · 3.3 V/5 V logic compatible input
- · Operates upto 800 kHz
- · RoHS compliant
