BLDC Motor Controller
3.3 BLDC Motor Control via CAN Bus Connection
In this sample application the IC can realize the driving of a BLDC motor via three external power N-FET half
bridges. Hall sensors are used to determine the rotor position. In case of battery break-down, the IC is still
capable to save sensitive data into the EEPROM, with the help of the energy stored in the 5V supply
capacitor. The current in both, the supply and ground path can be monitored. The SPI interface is used to
connect the IC to the CAN bus.
