600 V / 4 A, High-Side Automotive Gate Driver IC FAN7171-F085 Description The FAN7171-F085 is a monolithic highside gate drive IC that can www.onsemi.com drive highspeed MOSFETs and IGBTs that operate up to +600 V. It has a buffered output stage with all NMOS transistors designed for high pulse current driving capability and minimum crossconduction. ON Semiconductors highvoltage process and commonmode noise-canceling techniques provide stable operation of the highside driver under high-dv/dt noise circumstances. An advanced levelshift circuit offers highside gate driver operation up to V = 9.8 V S (typical) for V = 15 V. BS SOIC8 The UVLO circuit prevents malfunction when V is lower than the BS CASE 751EB specified threshold voltage. The highcurrent and lowoutput voltage-drop feature make this device suitable for sustaining switch drivers and energyrecovery ORDERING INFORMATION switch drivers in automotive motor drive inverters, switching power supplies, and high power DCDC converter applications.
