Overview
The FAN7085M-GF085 is a high-side gate drive IC designed for high-voltage and high-speed driving of MOSFET or IGBT, operating up to 300 V. This IC, produced by onsemi, utilizes a high-voltage process and common-mode noise cancellation technique to ensure stable operation under high-dV/dt noise conditions. The logic input is compatible with standard CMOS outputs, and the IC includes Under-Voltage Lockout (UVLO) circuits to prevent malfunction when the supply voltages are below the specified threshold. It is packaged in a space-saving SOIC-8 package, making it suitable for various applications requiring compact design.
