MST1180TS

MST1180TS is a dedicated IC designed for electric bicycle and motorcycle flasher controllers. With a DC voltage rating up to 45V, it significantly enhances the reliability of flasher controllers. The solution is streamlined, substantially reducing BOM cost, improving production efficiency, lowering product failure rate, and enhancing overall product quality. MST1180TS is compatible with existing series-connection circuit designs — simply connect it in series with the turn signal power line to enable flasher control functionality, making it easy to implement. MST1180TS integrates a fixed-frequency oscillator with comprehensive temperature compensation and voltage compensation, ensuring accurate flash frequency and stable, uniform operation across varying application environments. This enables a qualitative improvement in the overall performance of the flasher controller system compared to conventional discrete component solutions.
