The FAN3216TMX Gate Driver is a member of the PMIC (Power Management Integrated Circuits) family. It is designed to drive n-channel MOSFET (N-MOS) devices in power management applications. This device is capable of driving loads up to 25A DC at 78V and 270 kHz frequency with a low on-resistance range of 30mΩ. The device features an open-drain, constant-current sink configuration, allowing it to drive a variety of GateVoltage nodes with acceptable voltage drops. All functions of the device are implemented using a single FAN3216TMX chip.

The primary application field of FAN3216TMX Gate Driver is in DCDC converters, AC-DC front-end rectifiers or, power soft-start drives. With the use of FAN3216TMX, a higher efficiency, lower gate drive cost and improved converter performance can be achieved.

FAN3216TMX possesses several features that contribute to its effectiveness in various applications. Firstly, the device harnesses the latest power MOSFET technology in order to deliver excellent power dissipation at high switching frequencies and low on-resistance. Secondly, the on-resistance of the device is extremely low, enabling it to drive even lower load currents. Thirdly, the open-drain output stage offers improved dynamic control of Gate current. Lastly, the device has an adjustable output voltage and current sense pin.

The working principle of FAN3216TMX Gate Driver is based on the classic concept of input pulsing and output sinking. A logic level signal is applied to the device’s input which is then converted into a low resistance, high turning-on, current source driver through the internal push-pull output stage. This current source driver is then used to drive the switches or contacts of the power MOSFET device. In the case that the input signal switches from high to low, the output driver will switch off and the MOSFET’s drain pin will connect to the respective source pin, thus opening the switch. With the ability to quickly change device states, high frequency operations are made possible.

In conclusion, FAN3216TMX Gate Driver is a versatile and cost effective solution for power management and Gate driving applications. Its openness of design, relative low cost and quick switching speed make it an appropriate choice for many high frequency power management applications. This device is suitable for applications such as DCDC converters, AC-DC front-end rectifiers or, power soft-start drive.
