DESCRIPTION
The MP8042 is a dual channel power half-
bridge that can be configured as the output
stage of a Class-D audio amplifier. Each
channel can be driven independently as stereo
single ended audio amplifiers, or driven
complementary in a bridge tied load (BTL)
audio amplifier configuration.
The MP8042 features a low current shutdown
mode, standby mode, input under voltage
protection, thermal shutdown and fault flag
signal output. Both channels of the driver
interface with standard logic signals. The
MP8042 is available in a 20-pin TSSOP (with
Exposed Pad) package.
