LC898240-2H Application Field and Working Principle

LC898240-2H is a low power, low cost motor driver controller from the PMIC (power management integrated circuit) family. Designed specifically for applications in automobiles, LC898240-2H was developed as a low power solution to reduce the cost of motor control and motor steering. It is also used to reduce the power consumption while maintaining the same performance.

Application Field

LC898240-2H can be used to drive and control motors in a variety of applications including automotive, commercial, industrial and consumer. The demand for low power solutions is on the rise in these sectors. This controller has been designed with a low idle power consumption, which allows for the development of efficient systems. It can be used in a variety of applications such as door locks, steering systems, fuel pumps, steering locks, window lifts and more. It is also used to control the direction and speed of motors.

Working Principle

The working principle of LC898240-2H is based on the DC brushless motors. The controller is designed to drive three separate phases of a BLDC motor, and it can work with a wide range of operating motors. It offers a low voltage operating range of 8V to 12V, and the operating frequency can be adjusted from 200Hz to 20kHz.

The controller uses a current-controlled system to drive the motor and to adjust the speed and direction. The controller can detect the current drop at the motor’s phase winding, and it can adjust the output voltage accordingly to ensure the correct operation of the motor. It also provides a brake signal, which can be used to stop the motor. The controller has built-in protection against undervoltage, overvoltage and short-circuiting.

The LC898240-2H is also equipped with various other features such as current sensing, temperature sensing, fault detection, over temperature protection and protection against false triggering. The controller also provides protection against over and undercurrent. This can help prevent any motor damage or malfunction due to excessive current.

Conclusion

LC898240-2H is a powerful and economical motor driver controller from the PMIC family. It is designed specifically to drive and control motors in a variety of applications, and it is capable of operating in a wide range of voltage and frequency. The controller also offers protection against over and undervoltage, over temperature and false triggering. This makes it a perfect choice for applications which require precise speed and direction control.
