HI-RES GRAPHIC
The IRS2053M 200V driver IC for use in Class D
Audio applications including high performance
home theater systems and car audio amplifiers
requiring a compact footprint I based on IRs
class d audio amplifier topology. It integrates
three channels of high-voltage, high performance
half-bridge drivers with PWM modulators.

• Advantages
• The IRS2053M offers a Class D Audio solution with
  excellent sound quality, delivering a smaller
  footprint and higher power compared to
  alternative solutions when combined with IRs
  high efficiency power MOSFETs.
• When co-designed with the single channel
  IRS2092(S) and four channel IRS2093M, the
  IRS2053M offers the flexibility to configure 2.1
  channel, 6 channel and 6.1 channel applications.
• IRs extensive range of digital audio MOSFETs
  addressing output power from 50W to 150W are
  optimized for the IRS2053M to reduce component
  count and PCB space while achieving improved
  performance, efficiency, THD and EMI.
• The new devices comprehensive set of protection
  features includes programmable bi-directional
  current sensing to protect high- and low-side
  MOSFETs from over-current conditions. Other key
  features include logic compatible input and
  floating PWM input.

• Features
• 3 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
