The industry’s unique audio chip allows heavy vehicles to have high-quality car audio performance without adding any external components STMicroelectronics (STMicroelectronics, referred to as ST; New York Stock Exchange code: STM) launched the market's highest performance and ease of use of car audio power amplifiers. The new product is suitable for commercial vehicles such as trucks and buses with an electrical system operating voltage of 24V, as well as agricultural vehicles (car electrical system voltage is 12V). This is the world's first car with an operating voltage of 24V without any external components. The audio power amplifier that can directly drive the speaker proves STMicroelectronics' long-term focus and R&D investment in the automotive market. Luca Celant, Director of Audio and Power Marketing, Automotive Products Division, STMicroelectronics, said: "Millions of truck drivers and other heavy-duty vehicle drivers are usually alone driving long distances. The high-quality audio system helps them relax and concentrate. However, until now, they can barely use the existing audio system of heavy vehicles. With our leadership in the global automotive audio power amplifier market, STMicroelectronics has developed this unique product in the industry, allowing heavy vehicle drivers to enjoy High-quality audio that only new cars have." Car audio amplifiers must be able to withstand the impact of the harsh automotive environment, including high-intensity electrical noise, and must provide comprehensive protection against potentially dangerous accidents, such as short-circuit, load dump and chip overheat protection. The audio amplifier of the 12V car system is very sophisticated. Without adding external components, car audio manufacturers still cannot replicate the audio performance of the 12V system in the 24V car system. The addition of external components not only increases the cost, but even under certain conditions. There are still potential safety risks. ST's TDA7576B 24V audio power amplifier overcomes this problem. The product adopts the market-proven mass production semiconductor process technology BCD5, monolithic integrated power module and signal management module, more chip solutions are more cost-effective, and can withstand 60V peak power supply voltage without any damage. As the highest performance 24V system audio power amplifier on the market, TDA7576B adopts the same design principles and R&D investment as STMicroelectronics car radio power amplifiers. Therefore, heavy vehicle drivers can enjoy car-level high-quality audio systems. The TDA7576B audio amplifier further expands ST's 24V automotive-specific product portfolio, including the recently launched external lighting chips and internal lighting chips. The main features of TDA7576B: • 24V battery power supply; • High output power (2 x 20 W); • Significantly reduce the number of external components, such as no decoupling capacitors, no bootstrap capacitors, and no external compensation components; • Integrated power saving standby function; • Diagnostic output pin; issue a clipping, short circuit or overheating alarm; • Output DC compensation detection (offset detecTIon); • Protection function: 60V load dump protection, chip overheat protection, electrostatic discharge (ESD) protection, output GND or Vcc short circuit or load short circuit protection. TDA7576B is available now, in a compact MulTIwatt15 package.
