Description

MST1172 is a special integrated circuit for motorcycle flash controller. Dc voltage withstand up to 56V, greatly improve the reliability of

flash controller. The scheme is simple, greatly reducing  the  cost  of  the  scheme, improving  production  efficiency, reducing  product

failure efficiency and improving product quality.

MST1172 is compatible with the existing circuit concatenation design. It only needs to be concatenated on the power supply circuit  of

the turning lamp to realize the flash control function, which is convenient for application.

The built-in multiple protection mechanism can prevent the damage of the flash controller and the relevant power supply  line  on  the

motorcycle in some abnormal applications, and can automatically solve the protection after the application returns to normal. Improve

the reliability of the flash controller and reduce the repair probability of the whole motorcycle.
