The NJW4800 is a general purpose, half bridge power driver

capable of supplying 4A current. The internal gate driver drives

high-side/low-side power MOSFET; therefore, it has fast switching.

Additionally, it has protection features such as over current

protection and thermal shutdown.

And in the case of failure, it can output a fault flag.

It is suitable for power switching applications of DSP/micro

controller.
