ROHM Semiconductor BD16852AEFV-C 3-Phase Brushless Motor Driver

ROHM Semiconductor BD16852AEFV-C 3-Phase Brushless Motor Driver includes a power DMOS FET built in. It is mounted with a 120° commutation sensorless drive, which does not require a Hall device for position detection.

All output protections on the ROHM Semiconductor BD16852AEFV-C have a self-diagnostic and self-recovery function, and this can simplify the system configuration. Also, each output protection state can be judged easily by the protected alarm signal output function. It improves the set's traceability.
