FAN7190MX

FAN7190_F085 High-Current, High & Low-Side, Gate-Drive IC Features Description  Floating Channels for Bootstrap Operation to +600V 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.  Typically 4.5A/4.5A Sourcing/Sinking Current Driving Capability  Common-Mode dv/dt Noise Canceling Circuit  Built-in Under-Voltage Lockout for Both Channels 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.  Matched Propagation Delay for Both Channels  3.3V and 5V Input Logic Compatible  Output In-phase with Input Applications The UVLO circuit prevents malfunction when VDD and VBS are lower than the specified threshold voltage.  Diesel and gasoline Injectors/Valves  MOSFET-and IGBT high side driver applications 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 Ordering Information Part Number FAN7190M FAN7190MX Package Operating Temperature Range 8-SOP -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 May 2010 15V FAN7190_F085 RBOOT Up to 600V DBOOT HIN 1 HIN VB 8 LIN 2 LIN HO 7 Controller Q1 R1 CBOOT 3 COM VS 4 LO VDD 5 R2 6 OUTPUT Load C1 Q2 R3 R4 FAN7190_F085 Rev.01 Figure 1.
