MPQ7790GF-AEC1-P

MPQ7790 is an automotive grade, low-EMI, analogue input class-D audio amplifier which can drive mono speakers in a bridge-tied load configuration. It is a fully integrated audio amplifier that dramatically reduces solution size, featuring 300mohm power MOSFETs, start-up/shutdown pop elimination, short-circuit protection circuits, and EMI reduction technique. MPS class-D audio amplifiers exhibit the high fidelity of class-AB amplifiers at high efficiency. The MPQ7790 includes an internal circuit that allows the system to shut down automatically after the absence of an audio signal is detected. This feature is ideal for battery-operated systems. The MPQ7790 also has an adjustable power limit function. The PLIMIT circuit sets a limit on the output peak-to-peak voltage by limiting the duty cycle to a fixed maximum value. Typical applications include automotive E-call and telematic system. Available in a TSSOP-20 EP package.
