IRS2092
Description
The IRS2092 is a high voltage, high performance Class D audio amplifier driver with PWM modulator and protection. In conjunction with two external MOSFET and a few external components, a complete Class D audio amplifier with protection can be realized. International Rectifier's proprietary noise isolation technology allows high current gate drive stage and high speed low noise error amplifier reside on a single small silicon die. Open elements of PWM modulator section allow flexible PWM topology implementation.

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.

Note 1: Logic operational for Vs equal to -5 V to +200 V. Logic state held for Vs equal to -5 V to -VBS. Note 2: Nominal voltage for VREF is 5.1 V. IOREF of 0.3 - 0.8 mA dictates total external resistor value on VREF to be 6.3 k to 16.7 k. Note 3: GND input voltage is limited by IAAZ and ISSZ. Note 4: VSS ramps up from 0 V to 200 V. Note 5: Output logic status may not respond correctly if input pulse width is smaller than the minimum pulse width.
