Overview
The FAN7081MX-GF085 is a high-side gate drive IC designed by ON Semiconductor for high voltage and high speed driving of MOSFET or IGBT devices. This component operates up to 600V and is built using ON Semiconductor's high-voltage process, which ensures stable operation even in high-dV/dt noise environments. The IC features an advanced level-shift circuit, allowing high-side gate driver operation up to VS=-5V (typical) at VBS=15V. It is compatible with standard CMOS outputs and includes under-voltage lockout (UVLO) circuits to prevent malfunction when VCC and VBS are below specified threshold voltages. The device is available in a space-saving SOIC-8 package.
