FAN7081_GF085
High Side Gate Driver
Features
Description
• Automotive qualified to AEC Q100
The FAN7081_GF085 is a high-side gate drive IC designed for
high voltage and high speed driving of MOSFET or IGBT, which
operate up to 600V. Fairchild's high-voltage process and common-mode noise cancellation technique provide stable operation in the high side driver under high-dV/dt noise
circumstances. An advanced level-shift circuit allows high-side
gate driver operation up to VS=-5V (typical) at VBS=15V. Logic
input is compatible with standard CMOS outputs. The UVLO circuits prevent malfunction when VCC and VBS are lower than
the specified threshold voltage. It is available in a space saving
SOIC-8 Package. Minimum source and sink current capability of
output driver is 250mA and 500mA respectively, which is suitable for magnetic- and piezo type injectors and general MOSFET/IGBT based high side driver applications.
• Floating channel designed for bootstrap operation up to
+600V
• Tolerance to negative transient voltage on VS pin
• Common mode dV/dt noise cancelling circuit.
• Gate drive supply range from 10V to 20V
• Under-voltage lockout
• CMOS Schmit-triggered inputs with pull-up
• High side output out of phase with input (Inverted input)
• 8-Lead Small Outline Package (SO 8L NB)
SO 8L NB
Typical Applications
• Diesel and gasoline Injectors/Valves
• Common rail injection systems
• MOSFET-and IGBT high side driver applications
• Automotive motor and solenoid drivers

LIFE SUPPORT POLICY
FAIRCHILD’S PRODUCTS ARE NOT AUTHORIZED FOR USE AS CRITICAL COMPONENTS IN LIFE SUPPORT DEVICES OR SYSTEMS WITHOUT THE
EXPRESS WRITTEN APPROVAL OF FAIRCHILD SEMICONDUCTOR CORPORATION.
As used herein:
1. Life support devices or systems are devices or systems which, (a) are
intended for surgical implant into the bod y or (b) support or sustain
life, and (c) whose failure to perform when properly used in
accordance with instructions for use provided in the labeling, can be
reasonably expected to result in a significant injury of the user.
2. A critical component in any component of a life support, device, or
system whose failure to perform can be reasonably expected to
cause the failure of the life support device or system, or to affect its
safety or effectiveness.
AN TI-COUNTERFEITING POLICY
Fairchild Semiconductor Corporation's Anti-Counterfeiting Policy. Fairchild's Anti-Counterfeiting Policy is also stated on our external website, www.fairchildsemi.com,
under Sales Support.
Counterfeiting of semiconductor parts is a growing problem in the industry. All manufacturers of semiconductor products are experiencing counterfeiting of their parts.
Customers who inadvertently purchase counterfeit parts experience many problems such as loss of brand reputation, substandard performance, failed applications,
and increased cost of production and manufacturing delays. Fairchild is taking strong measures to protect ourselves and our customers from the proliferation of
counterfeit parts. Fairchild strongly encourages customers to purchase Fairchild parts either directly from Fairchild or from Authorized Fairchild Distributors who are
listed by country on our web page cited above. Products customers buy either from Fairchild directly or from Authorized Fairchild Distributors are genuine parts,
have full traceability, meet Fairchild's quality standards for handling and storage and provide access to Fairchild's full range of up-to-date technical and product
information. Fairchild and our Authorized Distributors will stand behind all warranties and will appropriately address any warranty issues that may arise. Fairchild will
not provide any warranty coverage or other assistance for parts bought from Unauthorized Sources. Fairchild is committed to combat this global problem and
encourage our customers to do their part in stopping this practice by buying direct or from authorized distributors.
