U2010B-MFP is an integrated motor driver developed by china-based Fairchild. It is specifically designed for driving a DC brush motor and generally used to control fans, pumps, and other motor-controlled applications. The integrated motor driver is made up of two integrated circuits; a low-voltage power MOSFET and a high-voltage posistor. It features a low on-resistance, a high frequency operation, a wide temperature range, and an efficient current efficiency.

The application fields of U2010B-MFP consist of industrial, automotive, and consumer electronic applications. It can be used for brushless DC (BLDC) or DC brushed motor control applications. The device can also be used for boosting power supply in automotive and industrial drives, as well as for powering high-output, long-term motor loads. This is because of its low RON, high frequency operation, and easy-to-control temperature range.

The working principle of U2010B-MFP involves a low-voltage, N-channel MOSFET and a high-voltage, Positive V-MOS reseat plus. The power MOSFET and the P-MOSFET plus conduct simultaneously, and form a positive voltage on the motor side. This positive voltage is then used to drive the motor. The power MOSFET and the P-MOSFET plus have a current- and voltage-sensing capability that allow for precise and dynamic control of the direction and speed of the motor. The working current of the MOSFET can be adjusted and optimized for different loads.

U2010B-MFP acts as a low-power, efficient motor driver, capable of controlling brushless DC or DC brushed motor applications. Its performance is further enhanced by the use of integrated gate driver components that provide the necessary functions for current and voltage sensing and control. This simple three-component motor driver provides a cost-effective, low-power and easy-to-use solution for controlling and driving motors in applications such as industrial control, automotive drives, and consumer electronic applications.
