FAN7382M1

PMIC - Gate Drivers

FAN7382M1 is a high-performance advanced 4A gate driver from Fairchild Semiconductor. It is their smallest such device ever produced and is part of their advanced power management integrated circuit (PMIC) family. This particular IC is designed for applications requiring very high efficiency and low power consumption, such as LED lighting, LCD display backlight applications and motor drivers.

Overview of FAN7382M1

FAN7382M1 has two inputs and four outputs which allow for a variety of topologies to be used in the application. The inputs are the voltage source, typically ranging from 14V to 30V, and a logic level input. The outputs can be configured as high side and low side drivers, totem pole, complementary and push-pull configurations. Each output is capable of providing up to 4A continuous current and over 10A peak current while maintaining a low on-resistance of 1.3Ω.

Features

FAN7382M1 has a number of features designed to make it a powerful and versatile solution for a variety of applications. It has a wide range of operating voltages, from 3.5V to 30V, allowing for a wide variety of applications. The gate voltage can be adjusted between 0.01V to 7V allowing for the gate level to be controlled. An auto shut-down mode is also available, which will shut off all current paths when triggered in order to conserve energy.

Application Fields and Working Principle

The FAN7382M1 can be used in a variety of applications, such as lighting, motors, displays, and entertainment systems. It is often used in LED lighting, where the high current capacity will drive multiple LEDs in parallel. The FAN7382M1 is also useful for motor drivers and other high current applications, as it can be easily configured to drive both high side and low side components.

The working principle of the FAN7382M1 is simple. The voltage source is connected to the two inputs and the logic level input is the control signal. Depending on the configuration, the two outputs can be connected to two different devices, such as two high side transistors and two low side transistors. When the logic level signal is low, the gate drivers will turn on, allowing current to flow from the voltage source, to the transistors and then to the loads. When the signal is high, the gate drivers will turn off, stopping the current flow.

Conclusion

The FAN7382M1 is a powerful and versatile gate driver designed for applications requiring high efficiency and low power consumption. It is designed to work with a wide range of voltage sources and can be configured for both high and low side signal requirements. Its low on-resistance and high current capacity make it suitable for a variety of applications, such as LED lighting, LCD display backlighting, and motor drivers.
