International Rectifier (IR) delivers IRS2053M 3-channel Class-D audio driver IC that integrates three channels of high-voltage, high performance half-bridge drivers with PWM modulators. Targeted at Class-D Audio applications, its compact footprint is suitable for home theatre systems and car audio amplifiers.

The device comes with a comprehensive set of protection features like programmable bi-directional current sensing to protect high- and low-side MOSFETs from over-current conditions. It also includes logic compatible input and floating PWM input. .

IR's range of digital audio MOSFETs addressing output power from 50W to 150W, are optimised for the IRS2053M to reduce component count and PCB space while achieving improved performance, efficiency, THD and EMI.

Pricing for the IRS2053M begins at Rs.250.15 ($5.60) each in quantities of 10,000-units. The device is MSL2

Industrial qualified and RoHS compliant.
