GENERAL DESCRIPTION

The EV8042DF-00C 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.
