The AM4951RMPTR-G1 is a monolithic, low-voltage (3 V to 5 V), high-performance three-phase brushless DC motor driver. It includes a power stage based on power MOSFETs and a controller based on a proprietary core that implements Field Oriented Control (FOC) with sensorless or sensor regulation. The motor power stage of the AM4951RMPTR-G1 enables precise current control both for 4-voltage controller (4V) and 8-voltage controller (8V) applications, depending on the configuration. It provides dynamic current control with current ripple cancellation (DCC), linearized low-loss PWM switching, and a sine-shaped motor current waveform. It also provides motor speed control in a wide range from full stop to full speed using the input signal, with a range of 2 KHz to 16 KHz.

The AM4951RMPTR-G1 is suitable for use in a range of applications, including brushless DC (BLDC) motors and single-phase switched reluctance (SR) motors. It provides a large range of features and functions, such as a three-phase PWM (Phase Lock Loop) controller, a single-phase PWM controller, a dual-phase commutation controller, and an embedded current controller used for field oriented control of the motor.

The AM4951RMPTR-G1 is designed for 3-phase motor applications with a motor current of up to 10 A. It offers a wide range of features and functions which make the device ideal for a variety of motor control applications. The device provides a wide range of current control modes, including direct and inductive current control, sine modulation, and quadrature modulation. It also provides motor speed control with a frequency of up to 16 KHz.

Working Principle: The AM4951RMPTR-G1 utilizes a two-level circuit structure with two dedicated MOSFETs to control the motor current. The two MOSFETs act as a single switch, allowing a way to control the motor current through pulse-width modulation (PWM). The PWM output is generated by a three-level based sinusoidal waveform and it is modulated to generate a sinusoidal waveform. The sinusoidal waveform provides precise control of the motor current by providing a smooth and linear output. The modulated signal is then used to control the motor current via the two MOSFETs.

The AM4951RMPTR-G1 also incorporates dual-phase commutation control. This allows for a bidirectional speed and torque control over the wide speed range covered with the device. The device also comes with an embedded current controller for field oriented control of the motor, allowing for precise and efficient control of the motor current.

In terms of safety, the AM4951RMPTR-G1 incorporates over-voltage protection, thermal shutdown, pre-charging of the gate drives, and locked rotor protection. It also includes an open-core detection circuit and a temperature alarm circuit that can time-out if the motor is running at too high a speed, or if there is an over-temperature condition.

Overall, the AM4951RMPTR-G1 is a versatile motor driver, suitable for a variety of motor control applications. With its wide range of features and functions, it is an excellent choice for brushless DC and single-phase switched reluctance motor control applications. The high performance and robust motor control made possible by the AM4951RMPTR-G1 make it an invaluable device for any motor control project.
