General Description
The NJU7343 is single-phase DC brushless motor driver IC designed for a small fan motor. Adopting the CMOS process, it can provide a low saturation output voltage that is effective in high current operation.It has Lock Detect / Auto Reset and Thermal Shutdown Circuit for safety fan operation, and it has FG output function as useful function.It is available in a small MSOP10 (VSP10) package, which makes motors thin and small. It is suitable for small and high output fan motor applications.
