FAN7081_F085  
High Side Gate Driver  
Features  
Description  
•
Qualified to AEC Q100  
The FAN7081_F085 is a high-side gate drive IC designed for  
high voltage and high speed driving of MOSFET or IGBT, which  
operates up to 600V. Fairchild's high-voltage process and com-  
mon-mode noise cancellation technique provide stable opera-  
tion 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 cir-  
cuits prevent from malfunction when VCC and VBS are lower  
than the specified threshold voltage. It is available with 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 gen-  
eral MOSFET/IGBT based high side driver applications.

DISCLAIMER  
FAIRCHILD SEMICONDUCTOR RESERVES THE RIGHT TO MAKE CHANGES WITHOUT FURTHER NOTICE TO ANY PRODUCTS HEREIN TO IMPROVE  
RELIABILITY, FUNCTION, OR DESIGN. FAIRCHILD DOES NOT ASSUME ANY LIABILITY ARISING OUT OF THE APPLICATION OR USE OF ANY PRODUCT OR  
CIRCUIT DESCRIBED HEREIN; NEITHER DOES IT CONVEY ANY LICENSE UNDER ITS PATENT RIGHTS, NOR THE RIGHTS OF OTHERS. THESE  
SPECIFICATIONS DO NOT EXPAND THE TERMS OF FAIRCHILD’S WORLDWIDE TERMS AND CONDITIONS, SPECIFICALLY THE WARRANTY THEREIN,  
WHICH COVERS THESE PRODUCTS.  
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 body 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.  
ANTI-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.
