22V, 4A Full-Bridge Driver



The MP8044 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 MP8044 features a low current shutdown mode, standby mode, input under voltage protection, current limit, thermal shutdown and fault flag signal output. Both channels of drivers interface with standard logic signals. The MP8044 is available in a 20-pin TSSOP package with exposed pad.
