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.

Recommended Operating Conditions
For proper operation, the device should be used within the recommended conditions below. The Vs and
COM offset ratings are tested with supplies biased at VAA-VSS=10V, VCC=VCC2=12V, COM2=COM and VBVS=12V. All voltage parameters are absolute voltages referenced to COM; all currents are defined positive
into any lead.

Logic operational for Vsn equal to –5V to +200V. Logic state held for Vsn equal to –5V to –VBSn.
Nominal voltage for VREF is 5.1V. IOREF of 0.3 – 0.8mA dictates total external resistor value on VREF
to be 6.3k to 16.7k ohm.
GND input voltage is limited by IIN-n.
Vss ramps up from 0V to 200V.
