Infineon Technologies 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.
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.
“With our highly integrated Motor System ICs, system designers only need half the board space compared to existing solutions. At the same time, system designers maintain the capability to choose their microcontroller,” said Andreas Doll, Vice President and General Manager, Automotive Body Power at Infineon. “Furthermore, we implemented our patented adaptive MOSFET driver that improves electromagnetic compatibility and reduces switching losses in the system.”
