FAN7313MX

FAN7313MX application field and working principle

FAN7313MX, a modern power management integrated circuit (PMIC), is designed to meet the requirements of various applications with its multifunctional features. This PMIC is mainly used in power supplies, especially in multi-rail designs. It can manage multi-rail power supply architectures with different power requirements and has superior system flexibility and expandability.

The FAN7313MX is an advanced high-end general-purpose multi-rail PMIC featuring efficient power management. It includes an advanced load switch, an adjustable step-down regulator, a low-noise linear regulator, and a DC-DC converter. The FAN7313MX has a 2.6V to 5.5V operational range, with up to 6A current handling capability and up to 600mV voltage delta between supply and output. It can be used to drive various sensors and small actuators, as well as small motors and LEDs.

The FAN7313MX works by controlling the flow of power through the switching of loads and other circuits, allowing for a more efficient use of energy. It controls and regulates the voltage and current output, helping to ensure that the correct voltage and current are supplied to the appropriate circuit. The switch is driven by a P-channel FET, which is controlled by the FAN7313MX’s regulators. When the switch is turned on, the FET is on and supplies power. When the switch is turned off, the FET is off and does not supply power.

The FAN7313MX offers multiple protection features, including over-current protection (OCP), over-voltage protection (OVP), over-temperature protection (OTP), reverse input protection (RIP), and soft start for smooth, safe operation. Additionally, the FAN7313MX has an advanced load monitoring and detection feature, which helps to maximize system efficiency and protect the connected load.

The FAN7313MX is a powerful, flexible, and cost-efficient PMIC designed to meet the needs of many industrial and consumer applications. It offers an efficient solution for multi-rail power supply architectures, while enhancing system flexibility and expandability.
