Power management integrated circuit (PMIC) is a chip used to manage the power flow between sources and loads. PMICs are usually used for automotive applications or to regulate power for embedded systems. The BA6428F-E2 is a highly integrated PMIC designed specifically for motor driver and controller applications.

The BA6428F-E2 is a single-chip, 2-phase brushless DC (BLDC) motor controller IC. It contains all the control, power, and protection circuitry required for the motor driver, such as PWM signals for the gate drivers, over-temperature protection, over-voltage protection, and an integrated motor protection circuit. The integrated gate drivers can provide a constant current of up to 1A and support voltage levels up to 20V.

The BA6428F-E2 employs a sinusoidal control scheme, which is a closed-loop control system that uses a signal derived from the motor speed to generate the appropriate voltage waveforms to drive the motor. It is capable of driving two motors with a maximum motor voltage of 30V and a maximum motor current of 1.2A. It also has integrated electrical protection features, including automatic power shut off and a thermal protection circuit.

The BA6428F-E2 also supports a variety of diagnostic functions, including motor temperature and current monitoring, as well as internal temperature sensing. It provides an integrated voltage regulator, providing a regulated supply voltage for the motor driver IC. The IC also includes an SPI interface, allowing communication between the controller and the motor driver IC.

In conclusion, the BA6428F-E2 is an integrated motor driver and controller IC optimized for BLDC motor applications. It contains all the necessary protection and diagnostic features for motor safety and accuracy, as well as an integrated voltage regulator for application flexibility. Its high current and voltage ratings make it ideal for automotive applications requiring precise control of high-power motors.
