FAN7171-F085
600V / 4A, High-Side Automotive Gate Driver IC
Description
Features
The FAN7171-F085 is a monolithic high-side gate drive
IC that can drive high-speed 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 cross-conduction.

Automotive qualified to AEC Q100
Floating Channel for Bootstrap Operation to +600 V
4 A Sourcing and 4 A Sinking Current Driving
Capability
ON Semiconductor’s high-voltage process and
common-mode noise-canceling techniques provide
stable operation of the high-side driver under high-dv/dt
noise circumstances. An advanced level-shift circuit
offers high-side gate driver operation up to VS=-9.8 V
(typical) for VBS=15 V.

Common-Mode dv/dt Noise-Cancelling Circuit
3.3 V and 5 V Input Logic Compatible
Output In-phase with Input Signal
Under- Voltage Lockout for VBS
25 V Shunt Regulator on VDD and VBS
8-Lead, Small Outline Package
The UVLO circuit prevents malfunction when VBS is
lower than the specified threshold voltage.
The high-current and low-output voltage-drop feature
make this device suitable for sustaining switch drivers
and energy-recovery switch drivers in automotive motor
drive inverters, switching power supplies, and high-
power DC-DC converter applications.
