FAN7081_GF085 High Side Gate Driver November 2009 High Side Gate Driver Features • Qualified to AEC Q100 • 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) FAN7081_GF085 Description The FAN7081_GF085 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. Typical Applications • Diesel and gasoline Injectors/Valves • MOSFET-and IGBT high side driver applications SOIC-8 For Fairchild’s definition of “green” Eco Status, please visit: http://www.fairchildsemi.com/company/green/rohs_green.html Ordering Information Device FAN7081M FAN7081MX X : Tape & Reel type Package SOIC-8 SOIC-8 Operating Temp. -40 °C ~ 125 °C -40 °C ~ 125 °C ©2009 Fairchild Semiconductor Corporation 1 www.fairchildsemi.com FAN7081_GF085 Rev. 1.0.0 FAN7081_GF085 High Side Gate Driver 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 VCC IN VB HO VS N.C 8 7 6 5 3 4 COM N.C 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_GF085 Rev. 1.0.0 www.fairchildsemi.com FAN7081_GF085 High Side Gate Driver Absolute Maximum Ratings Absolute Maximum Ratings indicate sustained limits beyond which damage to the device may occur.
