LM8364BALMF32/NOPB application field and working principle

The LM8364BALMF32/NOPB is a Power Management Integrated Circuit (PMIC) with supervisor functions that is ideal for use in power supply systems for computers, midrange servers, and workstations. It is designed to provide a centralized power management system that monitors and controls all the components of a power supply system, including the power supply components, system fans, and switching regulators.The LM8364BALMF32/NOPB addresses several problems encountered in multi-phase power management systems, such as inaccurate power sensing, irregular power delivery, and lack of fan speed control. It integrates several of the Supervisory functions required to monitor and control system power and performance, such as monitoring of pre-defined voltage ranges, monitoring system temperature, fan speed regulation, and voltage regulation.The LM8364BALMF32/NOPB features a Monitoring and Control Interface (MCI) that enables communication with the system’s other components. This MCI is used to collect and store power supply and temperature data, to which fan speed and voltage regulation can be applied. The MCI can be used to implement a variety of power management features such as power supply shut downs, system temperature alarms, and thermal protection. In addition to its MCI, the LM8364BALMF32/NOPB also features an internal Clock and Timer Unit (CTU), which can be used for a variety of timing functions such as fan speed measurement, tracking power supply current, and adjusting the system voltage.The LM8364BALMF32/NOPB is designed to provide high power efficiency, low power consumption, and thermal protection. It is highly configurable and can be customized to meet the requirements of a variety of systems. It supports up to 8 fan speed settings, multiple voltage points, and temperature protection levels, making it an ideal choice for power supply systems that require both efficient power management and flexibility.The LM8364BALMF32/NOPB is comprised of the following components:• MCI: The Monitoring and Control Interface (MCI) is used to communicate with system components and collect and store power supply and temperature data.• CTU: The Clock and Timer Unit (CTU) is used to measure and track system events, such as fan speed, power draw, and system voltage.• Voltage Sensor: The voltage sensor measures current voltage levels and provides over- or under-voltage protection.• Temperature Sensor: The temperature sensor is used to monitor and regulate the system temperature.• Control Logic Block: The control logic block is used to control the other components and to regulate system voltage, fan speed, and power draw.• Power Switching Block: The power switching block is used to control the switching of power from the power supply to the other components of the system.The LM8364BALMF32/NOPB is designed for use in power supply systems for computers, midrange servers, and workstations. It combines high power efficiency, low power consumption, thermal protection, and flexibility to provide a centralized power management system that is highly configurable to meet the requirements of a variety of systems.
