PMIC (Power Management Integrated Circuits) include devices for voltage regulation, power sequencing, power switching, or a combination of these functions. Motor Drivers and Controllers such as the ZXBM2003X10TC are devices intended to drive or control the direction and speed of a motor, like a brushless DC motor, using inputs from a control system or microcomputer.

Description

Models like the ZXBM2003X10TC consist of two small packages and are capable of sensing a variety of motor types and executing speed and direction control commands. This type of controller also offers a range of features that make it easy to use, such as built-in circuitry to detect a motor’s condition and operate in reverse and forward directions. The device is available in three versions, with different current ratings, optimized for operation of 9V, 12V and 24V motors, each with a maximum load of 10A.

Working Principle

Controllers such as the ZXBM2003X10TC have a highly integrated design, combining the control and drive functions onto a single chip. It integrates MOSFETs to provide the drive current and a current-sensing circuit to sense the Coil current of each phase, as well as a logic circuit for off/on delay and PWM braking. This type of controller also includes a built-in high-gain comparator, so it can quickly detect reverse current and ground short circuit faults, triggering the protection circuit and a fault signal output.

The ZXBM2003X10TC operates as a switch matrix that provides the Path and Commutation Signals. The path signal defines the direction of the rotation of the motor and the commutation signal identifies to the motor the next winding to energise. This type of controller stores multiple winding phases in its internal programs, which are cyclically sequenced. When the Dynamic Braking signal is activated in the logic input, the switching frequency is increased to a level set by the DBRTC Internal Program Counter Register, causing the motor to brake.

Application Field

Motor drivers and controllers such as the ZXBM2003X10TC are mainly used in various applications related to home appliances, such as washing machines and dryers, as well as in HVAC, medical, pumps and ventilation systems, and other applications that require motor control. They can also be used in the control system of a variety of robotic devices and applications, such as mobile robots, industrial robots and robotic arms, where precise motor control is required.
