It is also used in automotive motor drives, such as electric water pumps, steering systems, and door windows. Moreover, the LV8860V-TLM-H can be used in three-phase general purpose motor drives, as well as micro turbine and brushless pumps. In addition, it is suitable for both single-phase and two-phase AC or DC motor control.

Features

The LV8860V-TLM-H offers a variety of features, such as a low ON-resistance, small power consumption, and a wide voltage range. It also provides good system integration and high-level integration in its motor controller operations, making it highly suited for automotive and industrial applications.Moreover, the LV8860V-TLM-H offers a high operating temperature range and excellent ESD protection for integration of motor driver components. It also has a fast PWM (pulse width modulation) switching frequency of between 7 and 150kHz, allowing for faster motor control operations and better energy efficiency.

Working Principle

The LV8860V-TLM-H uses a PWM signal to control the motor driver operations. A high-frequency PWM signal is generated by an internal timer/oscillator circuit which is used to drive the power MOSFETs which control the motor. The PWM signal is used to adjust the speed of the motor by changing the duty cycle of the signal.The high PWM switching frequency of the LV8860V-TLM-H allows for high-precision motor control operations, as the motor’s speed can be accurately measured and adjusted in real-time. This also allows for better energy efficiency, as the motor’s speed can be adjusted according to the user’s demands, reducing the amount of energy wasted in excessive motor speed.

Conclusion

The LV8860V-TLM-H is an integrated circuit designed for automotive and industrial applications such as BLDC fan and pump motors, three-phase general purpose motors, and micro turbine and brushless pumps. It offers a number of features, such as a low ON-resistance, small power consumption, and a wide voltage range which make it ideal for motor controls applications. It runs on a high-frequency PWM signal which allows for precise motor control, and improved energy efficiency.
