NJW4800
30V/4A Half Bridge Driver
GENERAL DESCRIPTION
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.
