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 circum-
stances. 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.
