Overview
The FAN7382MX, produced by onsemi, is a monolithic half-bridge gate driver IC designed to drive MOSFETs and IGBTs that operate up to +600V. This IC utilizes onsemi's high-voltage process and common-mode noise canceling technique to ensure stable operation of the high-side driver even under high dv/dt noise conditions. The device features an advanced level-shift circuit that allows high-side gate driver operation up to VS = -9.8 V (typical) for VBS = 15V. The input logic level is compatible with standard TTL-series logic gates, and UVLO circuits for both channels prevent malfunction when VCC and VBS are lower than the specified threshold voltage.
