FAD8253MX-1中文资料1200V Half-Bridge Gate Driver, 2.5 A Source/3.4 A Sink, SOIC-8 package数据手册ONSEMI规格书

描述 Description

The FAD8253 is a monolithic half-bridge gate drive IC designed for high voltage, high speed driving IGBTs operating up to +1200V.
ON’s high-voltage process and common-mode noise canceling technique provide stable operation of high-drivers under high-dV/dt noise circumstances.
An advanced level-shift circuit allows high-side gate driver transient operation down to VS = -15V for VBS = 15V.
UVLO circuits tailored to IGBT as per FAD8253 IC to prevent malfunction when VDD and VBS are lower than the specified threshold voltage.
The output drivers of FAD8253 source/sink 2.5A/3.4A (typical), respectively, which is suitable for half-bridge and full-bridge applications in motor drive systems.
