FAN7190_F085 - High-Current, High & Low Side, Gate-Drive IC May 2010 FAN7190_F085 High-Current, High & Low-Side, Gate-Drive IC Features  Floating Channels for Bootstrap Operation to +600V  Typically 4.5A/4.5A Sourcing/Sinking Current Driving Description The FAN7190_F085 is a monolithic high- and low-side gate-drive IC, which can drive high speed MOSFETs and IGBTs that operate up to +600V. It has a buffered output stage with all NMOS transistors designed for high pulse current driving capability and minimum cross-conduction. Fairchild’s high-voltage process and common-mode noise canceling techniques provide stable operation of the high-side driver under high dv/dt noise circumstances. An advanced level shift circuit offers high-side gate driver operation up to VS=-9.8V (typical) for VBS=15V. The UVLO circuit prevents malfunction when VDD and VBS are lower than the specified threshold voltage. The high current and low output voltage drop feature make this device suitable for magnetic- and piezo type injectors and general MOSFET/IGBT based high side driver applications. 8-SOP Capability  Common-Mode dv/dt Noise Canceling Circuit  Built-in Under-Voltage Lockout for Both Channels  Matched Propagation Delay for Both Channels  3.3V and 5V Input Logic Compatible  Output In-phase with Input Applications  Diesel and gasoline Injectors/Valves  MOSFET-and IGBT high side driver applications Ordering Information Part Number FAN7190M FAN7190MX Package 8-SOP Operating Temperature Range -40C ~ 125C Eco Status RoHS Packing Method Tube Tape & Reel For Fairchild’s definition of “green” Eco Status, please visit: http://www.fairchildsemi.com/company/green/rohs_green.html. © 2010 Fairchild Semiconductor Corporation FAN7190_F085 Rev. 1.0.0 www.fairchildsemi.com FAN7190_F085 - High-Current, High & Low Side, Gate-Drive IC Typical Application Circuit 15V FAN7190_F085 RBOOT Up to 600V DBOOT HIN 1 HIN VB 8 Q1 Controller LIN 2 LIN HO 7 CBOOT R1 R2 3 COM VS 6 OUTPUT 4 LO VDD 5 C1 R3 Q2 Load R4 FAN7190_F085 Rev.01 Figure 1.
