The future of mobility will be dominated by electric vehicles (EVs) since this technology ensures that eco-friendly vehicles will be on our roads. However, the attractiveness of electromobility stands and falls with the batteries: maintaining the proper operating temperature for EV batteries is a critical component of the spread of EV across the world. If batteries are too hot, then the batteries will degrade faster, and safety becomes a concern. At lower temperatures, battery capacity and performance suffer. Therefore, thermal management of EVs are a key consideration for range, performance, lifetime and safety of EVs. Within the thermal management, smart actuators like water pumps, cooling fans, coolant & expansion valves and other actuators play a critical role to maintain the right temperature.
Infineon provides the key components in order to build the best cost-and-system-optimized smart actuator designs. The market for smart actuators is moving strongly towards small, mechatronic BLDC motor drive solutions and within that context, Infineon`s portfolio of MOTIX™ Embedded Power System-on-Chip motor drivers, Automotive MOSFET and Sensor portfolio is the right choice and state-of-the-art market integrated solution. Alternatively, if you require a solution for BLDC motor control applications which offer more computing power, AUTOSAR and embedded security functions (HSM, dual flash bank for OTA), we offer the TRAVEO™ II CYT2B6/ CYT2B7 microcontrollers with MOTIX™ BLDC Motor System IC TLE9563-3QX or TLE9564QX as a U-chip solution.
