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.

Absolute Maximum Ratings

Absolute Maximum Ratings indicate sustained limits beyond which damage to the device may occur. All

voltage parameters are absolute voltages referenced to COM; all currents are defined positive into any lead.

The Thermal Resistance and Power Dissipation ratings are measured under board mounted and still air

conditions.
