Power management integrated circuit (PMIC) refer to integrated circuits (ICs) that are designed to monitor and control the power consumption, including the supplies and voltages of one or more circuits. PMIC - Motor Drivers, Controllers contain components such as adjustable voltage-controlled power supplies and the outputs from these supplies can range from micro-amps to multi-amps. One such example is Fujitsu\'s Semiconductors\' BD63520EFV-E2.

The BD63520EFV-E2 is a dual-channel motor driver/controller for brushed DC motors. It comes with overcurrent protection as well as 6-PWM input and 3-fault signals. It supports two 2-phase brush DC motors via independent action, and with low power consumption, high-efficiency and high frequency PWM control, the drive current can be changed to meet the requirements of applications. It is possible to control the motor speed and direction, and adjust direction and speed without resetting.

In terms of the application fields, the BD63520EFV-E2 is best suited for medical-care or consumer electronic products such as electric toothbrushes, electric massagers and wearable devices. This is due to its low-voltage operation and the space-saving surface mount LQFP-48 package, offering the user high density mounting and heat dissipation, as well as a low profile, making it suitable for compact appliances.

The working principle of the BD63520EFV-E2 is based on Pulse-Width Modulation (PWM), which is often used to control the power of electric motors. This involves controlling the duration of a pulse in order to vary the power. With the BD63520EFV-E2, the user can input up to 6 PWM signals and the motor will consume power according to these signals. The user can also adjust the direction and speed of the motor without resetting, using the 3-phase outputs.

The BD63520EFV-E2 also provides protection from over-current, which will cut down the power automatically if it is determined that the motor is drawing more current than expected. This provides additional safety for the user in case of a malfunction.

Overall, the BD63520EFV-E2 could be considered a good choice for medical and consumer electronic applications. It is a low-voltage, space-saving device that provides protection from over-current, allowing for independent control of two brush DC motors and the ability to control speed and direction without resetting.
