IRS2452AM

Overview

The IRS2452AM is a two-channel integrated analog input Class D audio amplifier driver from Infineon Technologies. It operates with a VCC supply range of 10 V to 15 V and supports high-side floating supply offset voltages up to +/- 200 V. The device provides typical output currents of 0.5 A (Source) and 0.6 A (Sink). It features selectable dead-time generation options of 45, 65, 85, or 105 ns. Designed for half-bridge and full-bridge topologies, it utilizes a 32-pin MLPQ package measuring 7x7 mm.

Feature Summary

• Integrates two channels of high-voltage Class D audio amplifier drivers with built-in PWM modulators.
• Supports both differential and single-ended analog audio inputs for versatile system design.
• Includes programmable over-current protection and external thermal sensor input capabilities.
• Features click noise reduction and under-voltage protection mechanisms.

Applications

• High voltage half-bridge Class D audio amplifier designs
