FAN7081

FA N 70 81 _F 08 5 H igh Side G a te Dr iv e r March 2009 FAN7081_F085 Features • Qualified to AEC Q100 High Side Gate Driver Description 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 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 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 general MOSFET/IGBT based high side driver applications. • Floating channel designed for bootstrap operation up fully operational to + 600V • Tolerance to negative transient voltage on VS pin • dV/dt immune. • 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) Typical Applications • Diesel and gasoline Injectors/Valves • MOSFET-and IGBT high side driver applications SOIC-8 Ordering Information Device FAN7081CM FAN7081CMX X : Tape & Reel type Package SOIC-8 SOIC-8 Operating Temp. -40 ° C ~ 125 ° C -40 ° C ~ 125 ° C © 2008 Fairchild Semiconductor Corporation 1 www.fairchildsemi.com FAN7081_F085 Rev. 1.0.2 FA N 70 81 _F 08 5 H igh Side G a te Dr iv e r Block Diagrams VCC UV DETECT UV DETECT PULSE GEN HV Level Shift VB RQ R S PULSE FILTER HO IN VS COM Pin Assignments 1 2 3 4 VCC IN COM N.C VB HO VS N.C 8 7 6 5 Pin Definitions Pine Number 1 2 3 4 5 6 7 8 Pin Name VCC IN COM NC NC VS HO VB I/O P I P P A P Driver supply voltage Pin Function Description Logic input for high side gate drive output, out of phase with HO Ground NC NC High side floating offset for MOSFET Source connection High side drive output for MOSFET Gate connection Driver output stage supply 2 FAN7081_F085 Rev. 1.0.2 www.fairchildsemi.com FA N 70 81 _F 08 5 H igh Side G a te Dr iv e r Absolute Maximum Ratings Absolute Maximum Ratings indicate sustained limits beyond which damage to the device may occur.

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.
