PMIC - Gate Drivers are specific power management integrated circuits (ICs) that control the gate voltage and current supplied to the gate of a power MOSFET or IGBT to control the device conductivity. Power MOSFETs and IGBTs are used for a variety of switching applications, such as motor control, lighting, power supply design and many other applications. Because of their many applications, these devices have different packages, structures and shapes. This can range from small single channel packages to large multi-channel packages. In order to properly manage the gate voltage and current supplied to these devices, a specific type of power management IC is needed. One example is the FAN7081MX-GF085.

The FAN7081MX-GF085 is a single-channel logic-level gate driver designed specifically for low-side switching applications. It has a maximum gate drive current of 8A and is capable of driving MOSFETs and IGBTs from 3V to 15V. It is also capable of high switching speeds and is protected from short-circuit and reverse polarity conditions. The FAN7081MX-GF085 also comes with built-in fault protection in order to protect itself, the power MOSFET and IGBT from damage due to high current and temperature.

One of the main advantages of the FAN7081MX-GF085 is its low-side switching capabilities. By providing a 12V source voltage, the driver can switch the low-side power MOSFET or IGBT transistors on and off quickly, allowing for fast and reliable switching of the power devices. This is advantageous in many applications including power supply design, motor control, lighting and many other applications.

The FAN7081MX-GF085 works by using a logic-level transistor to control the gate voltage of the power MOSFET or IGBT. The logic-level transistor provides a variable gate drive voltage, allowing the power device to turn on at different levels. The logic-level transistor also serves to lower the switching speed of the power device, allowing it to be turned on and off more slowly. This can be very useful in applications such as power supply design and motor control.

When the FAN7081MX-GF085 is used for low-side switching applications, the power device being controlled must have a source voltage of 12V. This is because the logic-level transistor needs a minimum source voltage in order to switch the power device on and off. Once the source voltage is set, the FAN7081MX-GF085 can begin its switching process. The logic-level transistor will then control the gate voltage of the power device, allowing it to be turned on and off quickly and efficiently.

The FAN7081MX-GF085 can also be used in high-side switching applications. In these applications, the power device is switched using a high-side switch. This switch is typically controlled by a voltage or current source, allowing the power device to be switched quickly. The FAN7081MX-GF085 can also be used in high-side switching applications by providing a fixed gate voltage, allowing the power device to be turned on and off quickly.

In conclusion, the FAN7081MX-GF085 is a single-channel logic-level gate driver that can be used for low-side and high-side switching applications. It has a maximum gate drive current of 8A and is protected from short-circuit and reverse polarity conditions. The FAN7081MX-GF085 is versatile and can be used in many different applications, including power supply design, motor control and lighting.
