PMIC (Power Management IC) is a type of integrated circuit that are designed to manage the power consumption of electronic devices. PMICs come in many different varieties, and one type is motor drivers and controllers. BD6376GUL-E2 is an example of a motor driver and controller, and in this article we will discuss its application field and working principle.

The BD6376GUL-E2 is an automotive motor driver and controller, and its application field is the control of DC motors or 3-phase brushless DC (BLDC) motors for automotive applications. It is capable of up to 56V input operation and up to 6A maximum output current. It also features built-in protection functions, such as over/under-voltage detection and thermal shutdown.

The working principle of the BD6376GUL-E2 involves controlling the output current of a motor by amplifying the input current from a PWM signal. The PWM signal input is compared against the “Low” reference voltage, and the difference between the two signals is amplified to generate the output current. In order to ensure the accuracy of the control, the BD6376GUL-E2 has an integrated current sense amplifier. This amplifier is used to detect the difference between the output current and the current reference voltage, and adjust the output current accordingly.

In addition to its current control, the BD6376GUL-E2 also features a brushed DC motor control mode and a Hybrid Step Motor (HSM) control mode. The brushed DC motor control mode is used for controlling the direction and speed of a DC motor, and the HSM control mode is used for controlling the direction and speed of a 3-phase BLDC motor. The BD6376GUL-E2 also features a user-configurable Emergency Stop (ESTOP) function, which allows the motor to be safely stopped in an emergency situation.

Finally, the BD6376GUL-E2 also has a built-in voltage regulator, which is designed to provide a stable supply voltage to the motor driver and controller. The regulator provides an adjustable output voltage between 0.5V and 5V, and has a low output noise level to ensure precise motor control.

In conclusion, the BD6376GUL-E2 is an automotive motor driver and controller that is suitable for controlling DC motors and 3-phase BLDC motors. Its working principle is based on the amplification of an input PWM signal, and it features several user-configurable features to ensure precise motor control and safe operation.
