The LB11852FV-MPB-E is a motor driver, controller and integrated power management integrated circuit (PMIC) designed and manufactured by On-Semi, a leading semiconductor company. The device is designed to improve the efficiency and accuracy of motor control systems, providing a “single chip solution” for motor control applications.

The LB11852FV-MPB-E is a highly-integrated PMIC device, integrating a power management unit (PMU), a motor driver, and a control unit into one chip. The PMU is responsible for providing the power needed for the motor to run, and also for monitoring and regulating the power level. The motor driver is responsible for providing a current signal that controls the motor speed, while the control unit provides the algorithms and processes needed for the system to accurately control the motor.

The LB11852FV-MPB-E is designed for use in a variety of motor control systems, including automotive, industrial, medical and domestic applications (e.g. power washers, air conditioners, pumps). Thanks to its integrated PMU, the device can easily be configured and programmed to control various types of motors, including stepper, brushed and brushless motors. Additionally, the PMU enables a variety of efficient power management features, such as power saving modes, power limiting functions and overclocking, which all help to reduce energy wastage.

The LB11852FV-MPB-E device operates in three primary modes – standby, run and user-defined modes. In standby mode, the device is powered down, and all functions are disabled. In run mode, the device is powered up and the motor is operational. In user-defined mode, the user can program the device to operate in a custom configuration, allowing the user to customize the device’s behavior for a specific use case.

The device operates via a pulse width modulation (PWM) signal, which is used to control the power and speed of the motor. The PWM signal is generated by the control unit, and is then sent to the motor driver, where it is used to control the motor speed and power. The motor driver receives the PWM signal and outputs a current control signal, which is used to control the motor’s speed. The current control signal is continually monitored and adjusted by the PMU, ensuring the motor is always running at maximum efficiency.

The LB11852FV-MPB-E device is also designed with safety features, such as over-temperature protection and short-circuit protection, to prevent damage under abnormal operating conditions. Additionally, the device is designed to meet international standards, including UL and EMC, ensuring safe and reliable operation.

In conclusion, the LB11852FV-MPB-E is an advanced motor driver, controller and power management integrated circuit. Its highly integrated design provides an “all-in-one” solution for motor control applications, while its advanced features and safety features ensure that the system always operates safely and efficiently.
