Overview
The FAN7191MX-F085 is a monolithic high- and low-side gate-driver IC designed by onsemi. This device is capable of driving high-speed MOSFETs and IGBTs that operate up to +600V. It features a buffered output stage with all NMOS transistors, which provides high pulse driving capability and minimizes cross-conduction. The IC incorporates onsemi’s high-voltage process and common-mode noise canceling technique, ensuring stable operation under high dV/dt noise conditions. An advanced level-shift circuit allows high-side gate driver operation up to VS = -9.8V (typical) for VBS = 15V. Additionally, the UVLO circuit prevents malfunction when VDD and VBS are lower than the specified threshold voltage.
