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.

Operation
1. The EV0041 comes configured as a stereo single ended audio amplifier (EV0041A).
2. To configure the board as a full bridge circuit (EV0041B), short R4, R7, R9, remove C4, C7 and
stuff C12 with a 0.47µF capacitor.
3. Connect the audio inputs to the IN pins as shown in Figure 5.
4. Connect speakers to pins 1-4 as shown in Figure 5 for single ended configuration. Use pins 2 and
3 for bridged circuit.
5. Connect the power supply to the VIN terminals as shown in Figure 5.
6. SHDN enables/disables the MP8040. Drive SHDN low to turn on the MP8040, drive it high to turn
it off. If not used connect SHDN to GND.
7. A low output at FLT indicates that the MP8040 has detected a fault and has shutdown.
8. The DR pin is an optional fixed 5V voltage output capable of driving a 1mA load for external
circuitry.
