Description



Automotive qualified to AEC Q100
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.

Common-Mode dv/dt Noise-Cancelling Circuit
Floating Channel for Bootstrap Operation to +600 V
4 A Sourcing and 4 A Sinking Current Driving
Capability
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
The UVLO circuit prevents malfunction when VBS is
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
and energy-recovery switch drivers in automotive motor
drive inverters, switching power supplies, and highpower DC-DC converter applications.
Applications



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.

Typical Application
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.

Notes:
3. This IC contains a shunt regulator on VDD and VBS with a normal breakdown voltage of 25 V. 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.
4. Mounted on 76.2 x 114.3 x 1.6 mm PCB (FR-4 glass epoxy material).
5. 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.
6. 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
operating conditions are specified to ensure optimal performance. ON Semiconductor does not recommend
exceeding them or designing to Absolute Maximum Ratings.

Note:

turn on pulses (i.e., rising edge to the adjacent falling edge), turn off pulses (i.e., falling edge to the adjacent
rising edge) but also parasitic pulses induced by noise. Refer to Figure 25 and Figure 26. Value guaranteed by
design.
