Pioneering low cost solution for power amplifiers managing car engine start-stop feature

This article introduces a solution to avoid that the car audio amplifier will go into mute when the engine is in start-stop state. It is a trend that the car audio amplifier should work in normal mode even if the engine is in start-stop state. STMicroelectronics has used this solution in low cost device of TDA7850LV, which targets to fit the new generation of green transport.
