LB11852RV-MPB-H application field and working principle

LB11852RV-MPB-H is a motor control system designed and manufactured by Rohm. It is a general-purpose motor driver designed with a built-in power supply, current detection circuit and protection circuit, enabling the control of permanent magnet and brushless DC motors (PMDC motors) with greater power.

The LB11852RV-MPB-H can be used in a wide variety of applications such as home appliances, digital cameras, electric tools and automotive products. There are three types of application fields:

• Home Appliances: such as vacuum cleaners, blenders, fans, etc.
• Digital Cameras: such as single lens reflex cameras (SLR), camera lenses, etc.
• Automotive: such as fuel pumps, window lifters, sunroofs, etc.

The LB11852RV-MPB-H motor is controlled based on the PWM (Pulse Width Modulation) control by utilizing the internal current response circuit. The output voltage is generated according to the voltage command, and the output current is monitored by the current response circuit. This type of control is beneficial in cases where precise control is required and current protection is important.

The LB11852RV-MPB-H can control up to 4-phase motors and can be used in 8-speed control systems. The built-in PWM control circuit with current response and protection circuit provides excellent starting and stopping performance through precise control. The built-in overcurrent protection allows for reliable operation even in harsh environment.

The LB11852RV-MPB-H is a high-speed motor drive with a high efficiency driver and a built-in power supply. It can be used for various kinds of motor control applications such as for robotic arms, industrial servo motors, and AC servo motors. The drive is equipped with both linear and pulse-width modulation control, allowing for precise speed control and low noise operation.

The LB11852RV-MPB-H is well suited for applications such as medical products, industrial machinery, and automotive components. This motor drive is especially well-suited for applications that require low noise operation, precise speed control, and high efficiency.
