FAN7080_GF085 Half Bridge Gate Driver November 2009 Half Bridge Gate Driver Features • Qualified to AEC Q100 • Floating channel designed for bootstrap operation fully operational to + 600V • Tolerance to negative transient voltage on VS pin • VS-pin dv/dt immune. • Gate drive supply range from 5.5V to 20V • Under-voltage lockout • CMOS Schmitt-triggered inputs with pull-down • High side output in phase with input • IN input is 3.3V/5V logic compatible and available on 15V input • Matched propagation delay for both channels • Dead time adjustable FAN7080_GF085 Description The FAN7080_GF085 is a half-bridge gate drive IC with reset input and adjustable dead time control. It is 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 for both channels prevent from malfunction when VCC and VBS are lower than the specified threshold voltage. Combined pin function for dead time adjustment and reset shutdown make this IC packaged with space saving SOIC-8 Package. Minimum source and sink current capability of output driver is 250mA and 500mA respectively, which is suitable for junction box application and half and full bridge application in the motor drive system. Typical Applications • Junction Box • Half and full bridge application in the motor drive system SOIC-8 For Fairchild’s definition of “green” Eco Status, please visit: http://www.fairchildsemi.com/company/green/rohs_green.html Ordering Information Device FAN7080M FAN7080MX 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 FAN7080_GF085 Rev. 1.0.0 FAN7080_GF085 Half Bridge Gate Driver Block Diagrams VCC VB UVLO R vreg IN 500kΩ DEADTIME CONTROL PULSE GENERATOR PULSE FILTER R S Q HO VS vreg VCC VCC UVLO DELAY SD/DT 500kΩ LO COM Pin Assignments 1 2 3 4 VCC IN SD/DT COM VB HO VS LO 8 7 6 5 Pin Definitions Pine Number 1 2 3 4 5 6 7 8 Pin Name VCC IN SD/DT COM LO VS HO VB I/O P I I P A A A P Driver supply voltage Pin Function Description Logic input for high and low side gate drive output Shut down input and dead time setting Ground Low side gate drive output for MOSFET Gate connection High side floating offset for MOSFET Source connection High side drive output for MOSFET Gate connection Driver output stage supply 2 FAN7080_GF085 Rev. 1.0.0 www.fairchildsemi.com FAN7080_GF085 Half Bridge Gate Driver Absolute Maximum Ratings Absolute Maximum Ratings indicate sustained limits beyond which damage to the device may occur.
