BD16851AEKV-C (Under Development)
Three-phase Brushless Motor Pre-driver for Automotive
BD16851AEKV-C is a pre-driver IC for in-vehicle threephase brushless motor. It is a sensor-less drive that the hall devices for the position sensing are unnecessary and has a built-in speed control function. Input/output protections have a self-diagnosis and selfrecovery function, and it can simplify the system configuration. Also, each input/output protection states can be judged easily by the abnormal status signal output function. It improves traceability of the set.
