General Description
The FAN7371 is a monolithic high-side gate drive 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 VBS is lower than the
specified threshold voltage.
The high-current and low-output voltage drop feature makes this device
suitable for sustain and energy recovery circuit switches driver in the Plasma
Display Panel application, motor drive inverter, switching power supply, and
high-power DC-DC converter applications.
