FAN73711

FAN73711 — High-Current, High-Side Gate Drive IC June 2009 FAN73711 High-Current, High-Side Gate Drive IC Features „ Floating Channel for Bootstrap Operation to +600V „ 4A/4A Sourcing/Sinking Current Driving Capability „ Common-Mode dv/dt Noise Canceling Circuit „ 3.3V and 5V Input Logic Compatible „ Output In-phase with Input Signal „ Under-Voltage Lockout for VBS „ Built-In Shunt Regulator on VDD and VBS „ 8-Lead Small Outline Package (SOP) Description The FAN73711 is a monolithic high-side gate drive IC that can drive high-speed MOSFETs and IGBTs operating 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 VBS is lower than the specified threshold voltage. The high-current and low-output voltage drop feature makes this device suitable for sustain and energyrecovery circuit switches driver in the plasma display panel application, motor drive inverter, switching power supply, and high-power DC-DC converter applications. 8-SOP Applications „ High-Speed Gate Driver „ Sustain Switch Driver in PDP Application „ Energy Recovery Circuit Switch Driver in PDP Application...
