DESCRIPTION

The MP8040 is a general purpose, high frequency half bridge power driver capable of driving a 9A load. The devices integrates both top and bottom N-Channel MOSFET power switches and is fully protected from both sourcing and sinking current by a preset cycle-by-cycle current limit. It has a wide input voltage range from 7.5V to 25V.
