onsemi / Fairchild FAN73711 High-Current, High-Side Gate Driver IC
onsemi / Fairchild FAN73711 High-Current, High-Side Gate Driver ICs are monolithic high-side devices that can drive high-speed MOSFETs and IGBTs operating up to +600V. The FAN73711 has a buffered output stage with all NMOS transistors designed for high pulse current driving capability and minimum cross-conduction. onsemi / Fairchild 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 VBS is lower than the specified threshold voltage. The high-current and low-output voltage drop feature makes the FAN73711 gate driver ICs suitable for use in plasma display panels, motor drive inverters, switching power supplies, and high-power DC-DC converters.
