Description
The FAN7384 is a monolithic half-bridge 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 V_S = -9.8V (typical) for V_BS =15V.
The UVLO circuits prevent malfunction when V_DD and
V_BS are lower than the specified threshold voltage.
Output drivers typically source/sink 250mA/500mA,
respectively, which is suitable for half-bridge and full-
bridge applications in motor drive systems.
