Description

The FAN7382, a monolithic half-bridge gate-driver IC,
can drive MOSFETs and IGBTs that operate up to
+600V. Fairchild’s high-voltage process and common­mode noise canceling technique provides stable opera­tion of the high-side driver under high-dv/dt noise circum­stances. An advanced level-shift circuit allows high-side
gate driver operation up to V
VBS=15V. The input logic level is compatible with stan­dard TTL-series logic gates. UVLO circuits for both chan­nels prevent malfunction when V
the specified threshold voltage. Output drivers typically
source/sink 350mA/650mA, respectively, which is suit­able for fluorescent lamp ballasts, PDP scan drivers,
motor controls, etc.
