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.
