BD7763EFV-E2 Integrated Circuits (ICs)

The BD7763EFV-E2 is a fully integrated power management chip developed by ROHM Semiconductor for various motor-control applications. The chip enables efficient, power-saving motor control with wide dynamic range, wide current range, and noise-free, responsive operation. It features an outline shape that is easy to mount, noise prevention features for higher-speed and higher-precision motor control, current-feedback, and an extended frequency range (down to -40C) to cope with rapidly changing environments. The small size of the package, low cost, and the integrated driver enable compact and cost-effective designs.

The BD7763EFV-E2 supports many different applications, most notably automotive and industrial applications, such as engine control and powertrain performance tuning, robotics and automation, and other motion control applications. The device can be used to stroke motors, drive high-power linear solenoids and step motors, or drive any other motor whose inductive load requires a three-phase full-bridge configuration.

The BD7763EFV-E2 operates by providing a three-phase bridge output with a maximum drive current of 2.6A per phase. The device also has a sense line capability which provides enhanced overcurrent protection and allows more accurate current measurement to the motor. The IC features pulse-width modulation outputs for each phase, allowing for smooth and efficient control of the motor. The PWM outputs are generated by a built-in digital controller using a user-programmable duty cycle signal, which allows for precise control of the motor speed and torque.

The BD7763EFV-E2 operates in three different modes. The first mode is the "direct control mode". In this mode, the chip uses a fixed duty cycle to determine the speed of the motor and the set-point currents needed to reach that speed. The second mode is the "open loop current control mode". In this mode, the current in each phase is sensed and used to adjust the duty cycle, allowing for more precise control of the motor speed and torque. The last mode is the "closed loop current control mode", which uses an external reference to set the correct amount of current flowing in each phase. The BD7763EFV-E2 can be used in either mode, depending on the application.

The BD7763EFV-E2 includes various features to simplify integration into various applications. It is equipped with integrated circuits for controlling driver signals, current sensing, and monitoring, and its output phase current range is up to 2.6A per phase. The chip also integrates protection against over-voltage and under-voltage, short circuits, reverse power flows, and overcurrent. Additionally, the IC operates at a wide temperature range of -40C to 125C to meet the requirements of many applications.

The BD7763EFV-E2 is a low-cost, high-performance motor controller for a variety of applications. Its features, flexible control modes, and wide range of protection features make it a great choice for implementing motor control applications. The integrated features, wide temperature range, and small size of the chip allow for cost-effective and efficient designs. This makes it particularly suited for automotive and industrial applications that require high performance and precise motor control.
