Power management integrated circuit (PMIC) devotes itself to control the power of electronic systems and different components. The basic aim is to save energy and maximized the system performance. It is widely used in different electronic equipment nowadays. PMIC can be divided into several types, such as voltage regulator (LDO), battery charger, motor driver and controllers. Among these, motor driver and controllers are two common type of PMIC.

BD63860EFV-E2 is one type of PMIC motor drivers and controllers, which is developed by ROHM. It provides a low-voltage system for controlling low-voltage DC motors. The device offers a high current sinking and sourcing capability of 1.25 A. It provides an adjustable output voltage, which can be adjusted through external voltage divider circuits. This also provides a power saving solution while using multiple motors on a single board.

The application field of BD63860EFV-E2 includes automotive, home electronics, and office equipment. In automotive, it can be used in applications such as car window automatic control, car sunroof automatic control, power seat adjustment, and fan control. In home electronics, it can be used in vacuum cleaners and robotic commercial cleaners. In office equipment, it can be used in electric stapler, electric registration machine, and paper shredders.

The main function of BD63860EFV-E2 consists of electronic current limiting, output voltage limiting, and thermal protection. The voltage limit circuit limits the voltage between VIN and VOUT and shuts down the operating power supply when an overvoltage is detected. The electronic current limit adjustment circuit of this device sets the limit output current to suit the characteristics and duty cycle of each system. The device provides great protection features and designed for high reliability applications.

BD63860EFV-E2 consists of two driver ICs, H-bridge driver and gate drive circuit. The H-bridge driver includes two on-board field effect transistors (FETs), which have a high current sinking of up to 1.25 A each. It can control the motor with speed and torque control, while regulating the motor current. This device also configures the operating sequence and direction of the motor according to the specified duty cycle and RUN/STOP signal.

The gate drive circuit of BD63860EFV-E2 provides the drive current for each FET in the H-bridge driver, and the charge for the body diode of each FET. The gate drive current is adjustable from 0 to 20V. The device also provides short circuit protection and can operate from 4.5V to 24V.

In conclusion, BD63860EFV-E2 is one type of PMIC motor drivers and controllers, which is designed for low-voltage DC motor control applications. The device provides adjustable output voltage and can power multiple motors on a single board. It has many applications including automotive, home electronics and office equipment. The device also provides great protection features like electronic current limiting, output voltage limiting and thermal protection.
