Gate Drivers | FAD8253MX-1
概览
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.
