The Future of Analog IC Technology TM
DESCRIPTION
The MP8040 is a general purpose, high
frequency half bridge power driver capable of
driving a 9A load. The device 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.
