FAN7171 F085 High-Current High-Side Gate Drive IC April 2016 FAN7171 F085 High-Current High-Side Gate Drive IC Description Features The FAN7171 F085 is a monolithic high-side gate drive Automotive qualified to AEC Q100 IC that can drive high-speed MOSFETs and IGBTs that Floating Channel for Bootstrap Operation to +600 V operate up to +600 V. It has a buffered output stage with all NMOS transistors designed for high pulse current 4 A Sourcing and 4 A Sinking Current Driving driving capability and minimum cross-conduction. Capability Fairchilds high-voltage process and common-mode Common-Mode dv/dt Noise-Cancelling Circuit noise-canceling techniques provide stable operation of 3.3 V and 5 V Input Logic Compatible the high-side driver under high-dv/dt noise circumstances. An advanced level-shift circuit offers Output In-phase with Input Signal high-side gate driver operation up to V =-9.8 V (typical) S Under- Voltage Lockout for VBS for V =15 V. BS 25 V Shunt Regulator on VDD and VBS The UVLO circuit prevents malfunction when V is BS lower than the specified threshold voltage. 8-Lead, Small Outline Package The high-current and low-output voltage-drop feature make this device suitable for sustaining switch drivers Applications and energy-recovery switch drivers in automotive motor Common Rail Injection Systems drive inverters, switching power supplies, and high- power DC-DC converter applications.
