FAN7171_F085
High-Current High-Side Gate Drive IC
Features
Description
 Floating Channel for Bootstrap Operation to +600V
The FAN7171_F085 is a monolithic high-side gate drive
IC, which can drive high-speed MOSFETs and IGBTs
that operate up to +600V. It has a buffered output stage
with all NMOS transistors designed for high pulse current
driving capability and minimum cross-conduction.
 4A/4A Sourcing/Sinking Current Driving Capability
 Common-Mode dv/dt Noise Canceling Circuit
 3.3V and 5V Input Logic Compatible
 Output In-phase with Input Signal
 Under- Voltage Lockout for VBS
 25V Shunt Regulator on VDD and VBS
 8-Lead Small Outline Package (SOP)
 Qualified to AEC Q100
Fairchild’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=-9.8V (typical) for
VBS=15V.
The UVLO circuit prevents malfunction when VBS is
lower than the specified threshold voltage.
Applications
 High-Speed Gate Driver
 High-Power Buck Converter
 Motor Drive Inverter
The high-current and low-output voltage drop feature
makes this device suitable for sustaine switch driver and
energy recovery switch driver in the Plasma Display
Panel application, motor drive inverter, switching power
supply, and high-power DC-DC converter applications.

Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be operable above the recommended operating conditions and stressing the parts to these levels is not recommended. In addition, extended exposure to stresses above the recommended operating conditions may affect device reliability. The
absolute maximum ratings are stress ratings only. -40°C<=TA <=125°C unless otherwise specified.

Notes:
1)
This IC contains a shunt regulator on VDD and VBS with a normal breakdown voltage of 25V. Please note that
this supply pin should not be driven by a low-impedance voltage source greater than the VSHUNT specified in
the Electrical Characteristics section
2)
Mounted on 76.2 x 114.3 x 1.6mm PCB (FR-4 glass epoxy material).
3)
Refer to the following standards:
JESD51-2: Integral circuits thermal test method environmental conditions, natural convection, and
JESD51-3: Low effective thermal conductivity test board for leaded surface mount packages.
4
Do not exceed power dissipation (PD) under any circumstances.
Recommended Operating Conditions
The Recommended Operating Conditions table defines the conditions for actual device operation. Recommended
