Product Description

The MP8042 is a configurable full-bridge or dual channel 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, current limit, 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.

Kit details

The EV8042DF-00B is the evaluation board for the MP8042, a high current, dual channel power half-bridge. It accepts PWM modulated inputs for operation.

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