Auxiliary motor control in 12 V power distribution

Various automotive applications utilize electrical motors connected to the 12 V power distribution network. Depending on the use case, brushed DC motors are employed for shorter-term duty, while brushless DC motors (BLDC) are used for more demanding continous operating times. Infineon provides a wide portfolio of efficient and dependable semiconductor solutions, facilitating rapid time-to-market and reducing overall cost of ownership.
