FAN7385: 625V,3.3/5V input logic compatible 0.65/0.35A sink/source current, 2ch High Side Gate-Drive

The FAN7385 is a monolithic IC designed for high voltage, high speed driving MOSFETs and IGBTs operating up to +600V. Fairchild’s high-voltage process and common-mode noise canceling technique provide stable operation of high-side drivers under high-dv/dt noise circumstances. An advanced level-shift circuit allows high-side gate driver operation up to VS = -9.8V (typical) for VBS = 15V. The UVLO circuits prevent malfunction when VBS1 and VBS2 are lower than the specified threshold voltage. Output drivers typically source/sink 350mA/650mA, respectively, which is suitable for dual high-side switches and half-bridge inverters.
