MST1174KP

MST1174KP is a special integrated circuit for motorcycle flash controller. DC voltage withstand up to 45V, 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. When using the chip, simply connect the positive battery terminal to the chip's VIN pin, the VOUT pin to the bulb for connection, and a capacitor placed externally on the CEXT pin. Once a series switch connects the VOUT pin to the bulb, the device will begin to turn on/off with a 50% duty cycle. An external capacitor (47uF 25V) connected between the CEXT pin and the VOUT pin is used to store electrical energy to power the device during its conduction.
