MST1172TS-A：Support total power 30W and 30W within the incandescent lamp, fixed 1.42Hz flashing frequency, electric vehicle flapper chip

MST1172TS-A is a special integrated circuit for motorcycle flash controller. Dc voltage with stand  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.

MST1172TS-A 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.

MST1661TQ：Support total power 55W and 55W within the incandescent lamp, low load flashing frequency doubled, motorcycle flash chip

The MST1661TQ is a high-power flasher with a missing light indicator function. It is widely used in the field of motorcycles.

When using the chip, just connect the positive battery to the VIN pin of the chip, the VOUT pin to the light bulb, a capacitor is placed outside the CEXT pin, and once the series switch connects the VOUT pin to the light bulb, the device will start to turn on/off with a duty cycle of 50%.

An external capacitor connected between the CEXT pin and the VOUT pin is used to store electrical energy to power the device during on-off.

When a low load (output current below IDF) is detected, the flashing frequency is automatically doubled.

■ Complete direction indicator in a 3 PIN package

■ Double frequency flashing in low load conditions

■ Cycle by cycle over-temperature protection

■ Input voltage withstand up to 51V

■ Integrated clock circuit inside the chip, stable flashing frequency

■ Over current protection

■ Thermal shutdown protection

■ Typical on-state internal resistance 60mΩ

■ Available Packages : TO252-3
