Abstract
A motor controller comprises a driving circuit, a selection circuit, a sensorless control circuit, a Hall signal control circuit, a detection circuit, a first input terminal, and a second input terminal. The Hall signal control circuit may be coupled to a Hall sensor via the first input terminal and the second input terminal. When each of the voltage of the first input terminal and the voltage of the second input terminal is at a low level, the motor controller is operated in a sensorless driving mode. When one of the voltage of the first input terminal and the voltage of the second input terminal is at a high level, the motor controller is operated in a Hall control driving mode.
