3-Channel Class D Audio Driver
IC, IRS2053M
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 IR’s class d audio amplifier topology. It
integrates three channels of high-voltage, high performance
half-bridge drivers with PWM modulators.
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

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 IR’s 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.
• IR’s 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 device’s 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.
