Overview
The TAS5182DCAR is a stereo digital amplifier power stage controller designed to drive two discrete bridge-tied-load (BTL) MOSFET output stages. It delivers up to 100 W per channel at 6 Ω with efficiency exceeding 95%. The device accepts a 3.3-V digital PWM input and provides half-bridge independent control. It incorporates overcurrent, overtemperature, and undervoltage protection for the external MOSFETs. The component operates within a supply voltage range of 9 V to 12.6 V for gate drive and 3 V to 3.6 V for logic. It utilizes a low-profile 56-terminal TSSOP SMD package.
Feature Summary
- Stereo H-Bridge Controller
- Glueless Interface to TAS50XX Digital Audio PWM Processors
- Fault Detection including Overcurrent, Overtemperature, and Undervoltage Protection
Applications
- AV Receivers
- High Power DVD Receivers
- Power Amplifiers
- Home Theater
- Subwoofer Driver
Procurement Notes
Verify the specific ordering suffix 'R' indicates tape-and-reel packaging configuration. Confirm the commercial temperature range specification of 0°C to 70°C aligns with system requirements. Ensure compatibility with the TAS50XX series digital audio PWM processors for proper interface integration. Validate that the 56-pin HTSSOP DCA package dimensions fit the target PCB layout constraints.
Selection Notes
Select this component when designing high-power stereo audio systems requiring efficient digital amplification. It is suitable for applications needing integrated fault protection for discrete MOSFET stages. Consider the thermal performance of the PowerPAD package for heat dissipation management. Ensure the design supports the required 3.3-V digital interface and appropriate external MOSFET selection for the desired power output levels.
Part Context
The TAS5182 belongs to Texas Instruments' PurePath digital audio solutions family. It functions as a power stage controller rather than a complete amplifier, requiring external MOSFETs and a digital PWM processor. This architecture allows for flexible power configurations and high efficiency in professional and consumer audio equipment.

FAQ
How does the TAS5182 handle fault conditions?
The device includes built-in overcurrent, overtemperature, and undervoltage protection. These features safeguard the H-bridge and speakers against output short-circuits, overheating, and other fault conditions by driving outputs low or into a high-impedance state.
What type of input signal does the TAS5182 accept?
The TAS5182 accepts a stereo PWM 3.3-V input signal. It is designed to interface gluelessly with Texas Instruments TAS50XX digital audio PWM processors.
