A start-stop system aims at reducing the amount of engine idle time, by shutting down and restarting the internal combustion engine automatically when the vehicle stops. Thus, it contributes to improving fuel economy and reducing CO2 emissions. This is especially useful in urban environments where vehicles can spend significant amounts of time in traffic.
Start-stop operations require power electronics that can handle high current during cranking and ensure reliability during start stop cycles, operating on/off at high temperatures.
ST's solutions include silicon power MOSFETs, protections, gate drivers and microcontrollers, in accordance to AEC-Q100 and AEC-Q101 standards.
