Product Descriptions
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.
The MP8040 features a low-current shutdown mode, input under-voltage protection, thermal shutdown, and fault flag signal output. It interfaces with standard logic signals and is available in a small 8-pin SOIC with exposed pad package.
