Automotive Brushless Motor Driver ICs

For automotive electric pumps, we use sensor-less technology with hard logic control, which has a proven track record in many automotive applications. For HVAC blowers, sinusoidal drive technology provides a quiet and efficient motor drive. For EPS applications, we have a lineup of sensor input products that incorporate functional safety requirements. These automotive motor ASSPs meet the specifications required by customers for various applications and motorization needs. We provide automotive solutions that have qualified the Automotive Reliability Test (AEC-Q100).
