FAN73901

FAN73901 — High- and Low Side, Gate-Drive IC August 2008 FAN73901 High- and Low-Side, Gate-Drive IC Features „ Floating Channels for Bootstrap Operation to +600V „ Typically 2.5A/2.5A Sourcing/Sinking Current Driving Description The FAN73901 is a monolithic high- and low-side gatedrive IC, which can drive high-speed MOSFETs and IGBTs that operate up to +600V. It has a buffered output stage with all NMOS transistors designed for high pulse current driving capability and minimum cross-conduction. Fairchild’s high-voltage process and common-mode noise canceling techniques provide stable operation of the high-side driver under high dv/dt noise circumstances. An advanced level-shift circuit offers high-side gate driver operation up to VS=-9.8V (typical) for VBS=15V. The UVLO circuit prevents malfunction when VDD and VBS are lower than the specified threshold voltage. The high current and low output voltage drop feature make FAN73901 suitable for the switching power supply, motor driver, and high-power DC-DC converter applications.
