Overview
NJW4810A Dual Half Bridge Driver ■ GENERAL DESCRIPTION The NJW4810A is a general-purpose dual half bridge driver capable of supplying 1A current.
Output duty=100% can be operated by high side P channel MOSFET.
It can use as a full bridge driver by connecting VDD1 and VDD2.
The internal gate driver drives high-side/low-side power MOSFET; therefore, it is able to 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.
