About This Product

■Summary

The MPQ7790 is an automotive-grade, low-EMI analog input, Class D audio amplifier capable of driving mono speakers in a bridge-coupled load configuration. It is a fully integrated audio amplifier with a 300mΩ power MOSFET, start-up/shutdown, pop rejection, short-circuit protection, and EMI reduction techniques to dramatically reduce solution size. MPQ7790 applies BTL structure that can deliver 15W to 8Ω speaker with 16V power supply. MPS's class D audio amplifiers exhibit the high fidelity of class AB amplifiers with high efficiency. The MPQ7790 includes internal circuitry that allows the system to automatically shut down after the absence of an audio signal is detected. This feature is ideal for battery-powered systems. The MPQ7790 also has an adjustable power limit feature. The PLIMIT circuit sets a limit on the output peak-to-peak voltage by limiting the duty cycle to a fixed maximum value. You can think of this limit as a "virtual" voltage rail that is lower than the power supply connected to the PVCC. The MPQ7790 is offered in a TSSOP-20 EP package.
