NJW4801 . D U. 35V / 300mA Half Bridge Driver BCD Process Series GENERAL DESCRIPTION PACKAGE OUTLINE The NJW4801 is a general purpose, half bridge power driver capable of supplying 300mA current. The internal gate driver drives high / 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.
