MP7752
18V, 2x15W Stereo BTL, Fixed Frequency,
Inductorless Class-D Audio Amplifier
The Future of Analog IC Technology
DESCRIPTION
FEATURES
The MP7752 is an analog input inductorless
class-D audio amplifier, which drives stereo
speakers in bridge-tied-load configuration. It is
a fully integrated audio amplifier, which reduces
solution size dramatically. It integrates 240mΩ
power MOSFETs and short-circuit protection
circuits, and it features start-up/shutdown pop
elimination and advanced EMI performance.
Also, it is inductorless while passing the EMC
test.

TSSOP-28 EP Package
The MP7752 utilizes a stereo BTL structure
capable of delivering 15W per channel into 8Ω
speakers with a 16V power supply. MPS
class-D audio amplifiers exhibit the high fidelity
of class-AB amplifiers at high efficiency.
The MP7752 includes an internal circuit which
allows the system to shut down automatically
after the absence of the audio signal is detected.
This feature is used for energy-using products
and battery operated applications.
Adjustable Power Limiter
Automatic Shutdown with Zero Input Signal
Detection
Fault Output Flag
Also, it has an adjustable power limit function.
The PLIMIT circuit sets a limit on the output
peak-to-peak voltage. This is done by limiting
the duty cycle to a fixed maximum value. This
limit can be thought of as a "virtual" voltage rail,
which is lower than the supply connected to
PVCC.
APPLICATIONS
TV
DVD Receiver
Active Speaker
