IRS20957S High-Voltage Power Amplifier N Channel MOSFET

IRS20957S High-Voltage Power Amplifier N Channel MOSFET

The IRS20957S High-Voltage Power Amplifier is a protected Class D audio driver with a floating PWM (Pulse Width Modulation) input for high-voltage Class D audio power amplifier designs. It integrates the PWM controller and MOSFET driver stage, providing a cost-effective and simplified solution for high-power, high-fidelity audio applications. The IRS20957S is specifically optimized for high-efficiency, low-distortion, and robust performance.

DNA solutions, Nashik has various types of MOSFET's. Check out our complete collection of MOSFET's.

• High-Voltage Tolerant: Capable of operating with a high voltage rail up to 200V.
  

• Floating PWM Input: Allows flexibility in the input stage design and simplifies the circuit design.
  

• Integrated Dead-Time Generation and Shoot-Through Protection: Prevents cross-conduction of the MOSFETs, enhancing reliability and efficiency.
  

• Under-Voltage Lockout (UVLO) Protection: Prevents the operation of the device when the supply voltage is below the required threshold.
  

• Over-Current Protection (OCP): Provides protection against overcurrent conditions by shutting down the driver when an overcurrent event is detected.
  

• Over-Temperature Protection (OTP): Shuts down the driver to prevent thermal damage when the temperature exceeds the specified limit.
  

• Low Power Consumption: Designed for efficient power use, minimizing heat generation in the driver circuitry.
