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.
