The NCV7513AFTG is a part from ON Semiconductor\'s range of NCPXG motor drivers, controllers, and power management integrated circuits (PMICs). It is designed to provide an integrated solution for driving brushless DC (BLDC) motors and controlling power conversion systems in a variety of applications.

The NCV7513AFTG is an integrated BLDC motion/motor controller with integrated gate drivers, on-chip power management, and integrated power transistors. It is designed for use with N-channel power MOSFETS and can provide up to 10A continuous output current. The NCV7513AFTG is optimized for high efficiency at low duty cycles and low switching frequency (< 20 kHz). Its on-chip power management features include a three-phase current sensing and control system, a programmable over-temperature protection (OTP) circuit, and an automatic brownout protection (BOP) circuit.

The NCV7513AFTG is designed to minimize external components and simplify the design process. This is done by providing an integrated gate driver architecture, an integrated power management unit, an integrated current sensing circuitry, and comprehensive protection features. It also provides an integral Hall sensing circuit, allowing for more precise motor control.

The application fields of the NCV7513AFTG are diverse. It is suited for applications from consumer appliance motor controls such as remote-controlled fans and pumps, to industrial and automotive applications. These include robotic arm and wheel Motion controls, Electric scooter, E-bike, and Unicycle controls, Automotive HVAC controls, and others.

The working principle of NCV7513AFTG is based on the principle of brushless DC motor control, which involves the generation of three-phase sinusoidal currents which provide the motor with torque. The driver uses the Hall Sensor for position control information. The motor drive is then controlled by an on-chip control block which provides the necessary signals for the integrated gate drivers to drive 6 half-bridge power transistors.

The NCV7513AFTG contains on-chip current sensing circuitry, which monitors the current of each phase and compares it with a user-defined threshold. If it exceeds the user-defined threshold, protection circuitry is activated and the gate drivers disable. This protection feature ensures the system stays within safe operating parameters and extends its life.

The NCV7513AFTG provides variable speed operation and power management features. This allows the designer to reduce the power consumption of motor drive applications and to extend battery life. It also allows the designer to optimize the design for low noise and Motor EMI (electromagnetic interference).

In summary, the NCV7513AFTG is an optimized, integrated motor driver and controller solution for a wide variety of automotive, industrial, and consumer applications. It provides a robust, feature-rich motor drive solution with a low component count, wide operating temperature range, and low power consumption.
