FAN7385M

The FAN7385M integrated circuit is an advanced and versatile IC developed by Fairchild Semiconductor and is part of the Power Management IC (PMIC) family of products. This PMIC, specifically in the Gate Drivers segment, is designed to enhance the capabilities of FETs and other kinds of Power switching devices. Whether utilizing it to power a car audio amplifier system or to power a solar panel array, the FAN7385M is a trusted and reliable component.

The FAN7385M Gate Driver IC can operate safely from a wide range of supply voltages, from 3.2V to 48V and is capable of providing a maximum current of 2A. The FAN7385M also has high-side/low-side floating channels and can support push-pull or totem-pole output configuration. Furthermore, its Industrial Temperature Range of -40°C to 125°C ensures that it is compliant with most harsh environment applications.

The FAN7385M is designed to provide protection for the power switching devices such as floods, loads short circuit protection and inrush current limiting. It also includes a PWM signal to enable the current limit threshold to be adjusted, as well as an active pulling to enable higher noise immunity and 3-state enable.The FAN7385M also guarantees very low switching latencies, suitable to serve the most demanding applications.

This IC is capable of providing Advanced Load Switching Solutions, like High Side and Low Side configurations, Advanced ESD Protection, short circuit protection, and of driving Vortex Loads. All these features make it particularly suitable for automotive, industrial, and renewable energy applications.

The working principle of the FAN7385M is based on the combination of a drive stage and a load switch. The load switch senses the load current and a self-oscillating controller monitors and adjusts the voltage of the output stages in a closed-loop fashion, leading to a power transistor that is inherently limited in its current flow. The advanced self-oscillating current limit function operates at submicrosecond speed, providing fast loop response and protection against overloads.

The drive stage, on the other hand, is used to provide floating high side and low side channels. After the input is received, the FAN7385M will amplify it and then drive the power transistors, that are connected to the output, depending on the command.

In conclusion, the FAN7385M IC is an advanced and versatile integrated circuit, developed by Fairchild Semiconductor, suitable for a wide range of applications. The FAN7385M is part of the Power Management IC (PMIC) family of products and belongs to the Gate Drivers segment. With versatile features like its high-side/low-side floating channels and advanced load switching solutions, it is suitable for automotive, industrial, and renewable energy applications. It is an efficient and reliable source of power and can be trusted to provide reliable power to the most demanding applications.
