STMicroelectronics (STX; STM: STM), the world's leading supplier of automotive audio power amplifiers, has introduced the highest performance and ease-of-use in the market across multiple electronics applications, leading global semiconductor suppliers, and Car audio power amplifier. The new product is suitable for commercial vehicles such as trucks and buses with electrical system operating voltage of 24V, and agricultural vehicles (electrical system voltage of cars is 12V). This is the first in the world to install any external components in a car with an operating voltage of 24V. The audio power amplifier that can directly drive the speakers proves that the ST has a long-term focus on the automotive market and R&D investment.
Luca Celant, director of audio and power marketing at STMicroelectronics Automotive Products, said: “Several million truck drivers and other heavy vehicle drivers are usually driving alone, and high-quality sound systems help them relax and focus. However, until now, they can only reluctantly use existing audio systems for heavy-duty vehicles.Thanks to our leadership in the global automotive audio power amplifier market, STMicroelectronics has developed a unique product in this industry that allows heavy-duty vehicle drivers to enjoy Only high-quality audio is available in new cars."
Automotive audio amplifiers must be able to withstand the effects of harsh automotive environments, including high-intensity electrical noise, and must provide comprehensive protection against potentially hazardous events such as short circuits, load dumps, and chip overheating. The audio amplifiers of 12V automotive systems are very sophisticated. Without the addition of external components, car audio manufacturers are still unable to reproduce the audio performance of 12V systems in 24V automotive systems. Increasing external components not only increases the cost, even under certain conditions. There are still security risks.
ST's TDA7576B 24V audio power amplifier overcomes this problem. This product adopts the market-proven BCD5 mass-produced semiconductor process technology, monolithically integrated power module and signal management module, more chip solutions are more cost-effective, can withstand 60V peak power supply voltage and will not suffer any damage. As the highest performance 24V system audio power amplifier on the market, the TDA7576B uses exactly the same design principles and R&D investment as ST's automotive radio power amplifiers. Therefore, heavy-duty vehicle drivers can enjoy high-quality sound systems at the car level.
The TDA7576B audio amplifier further expands the 24V automotive-specific portfolio of ST semiconductors, including recently introduced exterior lighting chips and interior lighting chips.
The main features of TDA7576B:
• 24V battery power;
• High output power (2 x 20 W);
• Significantly reduce the number of external components, such as decoupling capacitors, bootstrap capacitors, and compensation components;
• Integrated power saving standby function;
• Diagnostic output pin; sends a clipping, short circuit, or overtemperature alarm;
• Output DC offset detection (offset detection);
• Protection functions: 60V load dump protection, chip overtemperature protection, electrostatic discharge (ESD) protection, output GND or Vcc short circuit or load short circuit protection.
