Abstract

The present invention relates to motor drivers, more specifically, to dc brushless motor drivers. The energy needed to power motor driver is provided through the terminals of output drivers. A self-regulated power device which does not require control signals from the driver, directs terminal signals to the voltage regulator and generating a chip internal reference voltage. The power device also acts as a buffer to reduce switching noises from disturbing chip internal voltage regulation. The aforementioned features allow for the omission of a dedicated power pin, and facilitate the selection of 3-pin miniature plastic packages. The use of such packages in dc brushless motor is espically beneficial when a magnetic sensor is included in the motor driver.
