This system shuts the engine off instead of idling while burning fuel and restarts it instantly on demand.
Stop/start systems require power electronics that can handle high current during cranking and ensure reliability during engine cycles operating on/off at high temperatures.
Freescale offers 8- and 16-bit MCUs plus analog switches, system basis chips (SBC) and transceivers for the numerous engine stop and start cycles.
The MM912J637 battery sensor fits with the start/stop system to monitor the current, voltage and temperature to inform the energy management system.
