Description
The FAN7888 is a monolithic three half-bridge gate-drive
IC designed for high-voltage, high-speed driving MOS-
FETs and IGBTs operating up to +200V.
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 350mA/650mA,
respectively, which is suitable for three-phase half-bridge
applications in motor drive systems.
