MST MST2219KC

MST2219 is a motorcycle ignition advance angle control IC. With an integrated internal oscillator, it implements advance angle control digitally, offering high accuracy and stability. The start and end advance angle speeds can be set using only two external resistors, making configuration simple and flexible. The ignition signal can simultaneously serve as an oscillation-stop signal output, with a maximum output current exceeding 10mA. It replaces discrete component solutions, simplifying design, reducing component count, lowering cost, and improving product performance and reliability.
