IRS2052M Description The IRS2052M integrates two channels of high voltage, high performance Class D audio amplifier drivers with PWM modulators and protections. In conjunction with external MOSFET and external components, a complete 2 channel Class D audio amplifier can be realized. The IRS2052M is designed with floating analog inputs and protection control interface pin especially for half bridge topology. High and low side MOSFET are protected from over current conditions by a programmable bi-directional current sensing. Essential elements of PWM modulator section allow flexible system design. A small MLPQ48 package enhances the benefit of smaller size of Class D topology. The IRS2052M is a lead-free, ROHS compliant.
