EVALUATION BOARD

General Description

The EV0041 is an evaluation board

designed to demonstrate the capabilities of

MPS’ MP8040. It can be configured as a

stereo single ended amplifier (EV0041A) or

a full bridge mono amplifier (EV0041B).

The MP8040 is a general purpose, high

frequency half bridge power driver. The

MP8040 integrates both top and bottom n-

channel MOSFET power switches. The

MP8040 is fully protected from both

sourcing and sinking current by a preset

cycle-by-cycle current limit. The MP8040

features a low-current shutdown-mode,

input under-voltage protection, thermal

shutdown, and fault flag signal output. The

MP8040 interfaces with standard logic

signals and is available in small 8-lead

SOIC package.
