产品描述

The MP8046 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 MP8046 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 MP8046 is available in a 20-pin TSSOP (with Exposed Pad) package.

High Current, Dual Channel Power Half-Bridge Evaluation Board

The EV8046DF-00A is the evaluation board for the MP8046, a high current, dual channel power half-bridge. It accepts PWM modulated inputs for operation.

The MP8046 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 MP8046 is available in a 20-pin TSSOP (with Exposed Pad) package.
