Our car audio amplifiers provide the traditional clean and powerful sound that users have come to expect, as well as all the protection and safety features needed to make our devices robust in an automotive environment. ST has a complete family of green-power products specifically designed to be compliant with advanced technologies for cleaner cars, such as engine start/stop. ST’s product portfolio includes class AB, SB (high efficiency), SB-I (improved high efficiency) and class D devices, with or without an I²C interface, and with analog or digital inputs. We offer a range of packages and pin-to-pin compatible ICs, covering different power requirements and supporting one to four channels. What’s more, ST has a wide multifunctional voltage regulator portfolio that meets all automotive infotainment needs. They are protected against load dump and support battery voltage variations and transients, providing multiple linear or switching voltage outputs, with or without an I²C bus, and have a very low standby quiescent current.
