From power lift gate and sunroof to electric seat adjustment and fuel pumps, an increasingly large number of electric motors ensure safety and comfort in modern cars. Infineon Technologies AG is now presenting a new product family called Motor System ICs designed for control of both brushed and brushless DC motors. These ICs are the world’s first multiple half-bridge drivers for MOSFETs with integrated power supply and communication interfaces.
In terms of integration, the new Motor System ICs complement the existing Infineon motor control IC portfolio, ranking between discrete solutions and highly integrated embedded power products that include an ARM processor. The new product family comprises a total of seven variants, all in a VQFN-48 package (7 mm x 7 mm).
The devices contain up to four half-bridge drivers for external N-channel MOSFETs. An integrated linear voltage regulator supplies 5 V with an output current of 250 mA. A CAN-FD transceiver with 5 Mbit/s according to ISO 11898-2:2016 which includes partial networking option and/or a LIN transceiver according to 2.2A / ISO 17987-4 and SAE J2602 are available for communication.
Development samples for the first devices are available. Series production is scheduled to start in the fourth quarter of 2020.
