PRESS RELEASE
DATA SHEETS
The IRS2093M(TR)PbF integrates four channels of
high voltage, high performance Class D audio
amplifier drivers with PWM modulators and
protections. In conjunction with external
MOSFETs and external components, a complete 4
channel Class D audio amplifier can be realized.

• Advantages
• The IRS2093M offers a smaller size Class D audio
  solution with excellent audio performance.
• Compared to alternative solutions, an IRS2093M
  based solution achieves a smaller footprint and
  high power due to the high efficiency of IRs
  digital audio MOSFET.
• High and low side MOSFETs are protected from over
  current conditions by a programmable
  bi-directional current sensing.
• A small MLPQ48 package enhances the benefit of a
  smaller size of Class D topology.
• The advantage of Class D over Class AB is that
  performance improvement comes directly from
  silicon improvement and this is where IR has the
  advantage by providing both the IC and FET.
• The IC is rated at 200V while the FET rating can
  vary from 55V to 200V depending on the amplifier
  power.

• Features
• 4 channel integrated analog input Class D audio
  amplifier drivers in a 48 pin MLPQ package
• Programmable over current protection
• Programmable dead-time generation
• Versatile protection control enabling latched,
  non-latched, or host controlled shutdown function
• Versatile input structure for self-oscillating
  PWM, external clock synchronization, or natural
  carrier based PWM modulations
• Start and stop click noise reduction
• Under voltage protection
• High noise immunity
