FAN7384M集成电路（IC）的栅极驱动器规格书PDF中文资料

描述 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 VS= -9.8V (typical) for VBS=15V. The UVLO circuits prevent malfunction when VDD and VBSare lower than the specified threshold voltage. Output drivers typically source/sink 250mA/500mA,

respectively, which is suitable for half-bridge and full bridge applications inmotor drive systems.
