TAS5182IDCARG4

Overview

The TAS5182IDCARG4 is a stereo digital amplifier power stage controller manufactured by Texas Instruments. It operates within a supply voltage range of 9 V to 12.6 V for the gate drive and 3 V to 3.6 V for logic. The device supports an operating frequency of 1500 kHz and delivers up to 2x100 W RMS at 6 Ω in bridge-tied-load configuration. Typical total harmonic distortion plus noise is less than 0.15% at 100 W into 6 Ω at 1 kHz. It utilizes a low-profile 56-terminal TSSOP surface-mount package with a thermal pad.

Feature Summary

• Stereo H-Bridge Controller designed to drive discrete MOSFET output stages
• Glueless interface compatibility with TAS50XX digital audio PWM processors
• Integrated fault detection including overcurrent, overtemperature, and undervoltage protection
• Independent half-bridge control with adjustable dead-time programming

Applications

• AV Receivers
• High Power DVD Receivers
• Power Amplifiers
• Home Theater Systems
• Subwoofer Drivers

Procurement Notes

Verify the specific suffix IDCARG4 against the latest Texas Instruments documentation to confirm active status and packaging details. Ensure the design accommodates the required external MOSFETs and bootstrap capacitors as specified in the application schematics. Confirm that the PCB layout supports the thermal requirements of the 56-pin DCA package for reliable operation.

Selection Notes

Select this component when designing high-power stereo digital amplification systems requiring direct interfacing with TI digital audio PWM processors. It is suitable for applications demanding high efficiency exceeding 95% and robust protection mechanisms for discrete MOSFET bridges. Consider the 56-pin package constraints and thermal management needs during the initial hardware architecture phase.

Part Context

This device belongs to the TAS5182 family of stereo digital amplifier power stage controllers. It functions as the driver stage for PurePath technology-based audio solutions, working in conjunction with TAS50XX series processors. The component enables true digital audio amplification by controlling external H-bridges, distinguishing it from integrated mono or multi-channel Class-D amplifiers.
