Description
The FAN7385 is a monolithic high side gate drive 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.
