Working Principle

FAN7171MX-F085 is an unipolar driver, meaning it can drive either an nMOSFET or pMOSFET. It has low operating losses and can switch MOSFETs at frequencies up to 1MHz. It includes both a high side and low side driver, which are individually controllable using separate inputs. Other features include programmable dead time to eliminate shoot-through currents, negative voltage operation extending gate drive capability, and a hi-resolution timer and oscillator frequency adjust mechanism. By controlling the gate of the MOSFET, the FAN7171mx step-up gate driver is able to transfer the voltage from a lower voltage source to a larger voltage load.

The FAN7171mx is designed specifically for driving both n- and p-channel MOSFETs for buck, boost, and flyback applications. It provides an adjustable oscillator frequency to achieve high efficiency, low EMI operation, and a programmable dead time to prevent shoot through current.

The FAN7171mx\'s compatibility with both n- and p-channel MOSFETs makes it ideal for a variety of applications, from LED lighting and power management to automotive and audio applications. Plus, its wide input voltage range and high peak output source and sink currents enable it to withstand tough operating conditions, even in the most demanding applications.
