Infineon Technologies IRS20957S | Demoboard IRAUDAMP6-DB_TOLLGaN
Protected Digital Audio Driver with Floating PWM input in a 16-Lead SOIC Narrow Package
Overview
| Topology | Other Topology |
| IC revision | 2 |
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.
Features
- Floating PWM input enables easy half bridgeimplementation
- Programmable bidirectional over-current protection withself-reset function
- Programmable preset dead-time for improved THDperformances
- High noise immunity
- +/-100V ratings deliver up to 500W in output power
- 3.3 V/ 5 V logic compatible input
- Operates up to 800kHz
Typical applications
- Home theatre systems / Mini component stereo systems / Powered speaker systems / General purpose audio power amplifiers
