IRS2093MPbF
Description
The IRS2093 integrates four 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 4 channel Class D audio amplifier can be realized. The IRS2093 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.

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.
