LV8712T-MPB-H

Power Management Integrated Circuits (PMICs) are essential components of any system design, enabling system designers and engineers to redistribute power to different parts of the system. PMICs play the role of managing power for the rest of the system, enabling efficient and accurate power distribution, maintaining overall system stability and performance, and providing added features such as over-current and over-voltage protection. The LV8712T-MPB-H is a PMIC from ON Semiconductor that is specifically designed for motor driver/controller applications, providing a range of features for high-performance and reliable power management in these applications.

The LV8712T-MPB-H is a non-isolated step-down DC/DC converter with four outputs, each of which has its own independent output voltage and switch independently of the others. This makes the LV8712T-MPB-H ideal for applications requiring multiple independent power rails to be supplied with a single voltage input. The output voltage and current of the converter is adjustable via its digital control pins, making it very flexible for different applications and end-user requirements. In addition, the LV8712T-MPB-H also features an integrated gate driver for driving external N-channel MOSFETs for synchronous rectification, low standby current, and a wide operating temperature range.

The LV8712T-MPB-H is suitable for a wide range of motor driver and controller applications, allowing the user to reduce board space, reduce components and overall system cost, and improve system reliability. These applications include motor driver boards, motor controllers, fan motor controllers, solenoid motor controllers, and many others. Furthermore, the LV8712T-MPB-H can also be used in power distribution systems, power management in industrial equipment, automotive applications, and consumer electronics.

The working principle of the LV8712T-MPB-H is based on the pulse width modulation (PWM) technique. This technique involves switching the output of the converter on and off in order to regulate its output voltage and current. The output voltage of the converter is determined by its internal feedback loop, which compares the output of the converter to its internal reference voltage, and adjusts the duty cycle of the converter accordingly in order to maintain the required output voltage. The output current of the converter is determined by its power stage, which can be configured to operate in either continuous or discontinuous conduction mode (CCM or DCM) depending on the system requirements.

The LV8712T-MPB-H is a highly integrated PMIC that provides a cost-effective solution for motor driver/controller applications. Its integrated gate driver, adjustable output voltage, wide operating temperature range and wide input voltage range make it an ideal choice for a wide range of motor driver and controller applications. Furthermore, its extremely small package footprint makes it ideal for space-constrained applications. It is therefore an excellent solution for motor driver/controller applications where board space, efficiency and reliability are of paramount importance.
