The BD68620EFV-E2 is a high-level integrated motor driver IC from ROHM Semiconductor that offers users a wide range of applications and benefits. The IC is a low-voltage (1.8 V to 12 V) designed to operate over a wide temperature range of -40 to +80°C. It features a multi-functional 3-phase motor driver, an H-bridge driver, and integrated protection functions including overcurrent, undervoltage and thermal fault detection. In addition, it includes an 8-bit digital-to-analog converter (DAC), analog-to-digital converter (ADC), and bidirectional digital output.

The BD68620EFV-E2 is ideal for driving motors in industrial applications such as conveyer belts, medical equipment, washing machines, pumps and compressors. It can also be used to control electric or hydraulic valves, or to provide motion control for robots.

The IC offers a wide range of protection functions, including short-circuit protection and loss detection. It is designed to protect the motor from overcurrents and short circuits, providing reliable operation. It also enables the motor to start up smoothly even when the motor is connected to a low-impedance load. Furthermore, the IC supports two-phase and three-phase motor applications, providing a wide range of flexibility to support various kinds of motor applications.

In addition to control and protection functions, the BD68620EFV-E2 includes three independent operational amplifiers that can be used to implement current- and torque-feedback mechanisms. The IC also features a PWM generator with adjustable frequency and variable duty cycle, which can provide flexible control of the drive system. The integrated current sensors help reduce the current ripple that can occur when the motor is running under load.

The working principle of the BD68620EFV-E2 involves the use of the integrated H-bridge driver. This allows users to switch the polarities of the motor current in order to control the motor direction and speed. The current sensor can detect the current flow in the motor while the three operational amplifiers are used to implement current- and torque-feedback mechanisms. The PWM generator can generate a variable duty cycle signal in order to adjust the speed, torque and current of the motor.

The BD68620EFV-E2 is a powerful motor driver IC that offers a wide range of features and benefits. It is well-suited to industrial applications, enabling users to implement current- and torque-feedback systems. The integrated H-bridge driver, current sensors, and PWM generator enable users to control the speed and direction of the motor. Its low-voltage (1.8 V to 12 V) design and high-temperature operating range make it well-suited for industrial applications, and its protection functions mitigate the risks of damage to the motor and system.
