Overview
The FAN7383MX is a half-bridge gate-drive IC produced by onsemi, designed for driving MOSFETs and IGBTs that operate up to +600V. This IC features onsemi’s high voltage process and a common-mode noise canceling technique, ensuring stable operation of high-side drivers even under high-dv/dt noise conditions. The advanced level-shift circuit allows high-side gate driver operation up to VS = -9.8V (typical) for VBS=15V. The IC also includes built-in UVLO (Undervoltage Lockout) functions for both channels to prevent malfunction when VDD and VBS are lower than the specified threshold voltage.
