The IRS2452AM integrates two channels of high voltage, high-performance Class D audio amplifier drivers with PWM modulators and protections. In conjunction with external MOSFET, the IRS2452AM forms a complete 2 channel Class D audio amplifier. The IRS2452AM is designed with floating analog inputs and protection control interface pins convenient for half-bridge applications. High and low side MOSFETs are protected from over current conditions by a programmable over current protection. Essential elements of the PWM modulator section allow flexible system design.
