Description
The FAN73711 is a monolithic high-side gate-drive IC
that can drive high-speed MOSFETs and IGBTs operating up to +600 V. 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=-9.8 V (typical) for
VBS=15 V. 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 as a sustain and energyrecovery circuit switch driver in plasma display panel,
motor drive inverter, switching power supply, and highpower DC-DC converter applications.
