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 V S=-9.8V (typical) for VBS=15V. The UVLO circuit prevents malfunction when V DD 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

The device may not function or be opera- ble above the recommended operating conditions and stressing the parts to these levels is not recommended. In addi- tion, extended exposure to stresses above the recommended operating conditions may affect device reliability. The absolute maximum ratings are stress ratings only. -40C <=TA<= 125C, unless otherwise specified. Notes: 2. Refer to the following standards: JESD51-2: Integral circuits thermal test method environmental conditions - natural convection JESD51-3: Low effective thermal conductivity test board for leaded surface mount packages 3. Do not exceed P D under any circumstances. Recommended Operating Conditions The Recommended Operating Conditions table defines the conditions for actual dev ice operation. Recommended operating conditions are specified to ensure optimal perfor mance to the datasheet specifications. Fairchild does not recommend exceeding them or designing to absolute maximum ratings.
