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 V_S=-9.8V (typical) for
V_BS=15V.
The UVLO circuit prevents malfunction when V_BS is
lower than the specified threshold voltage.
The high-current and low-output voltage drop feature
makes this device suitable for sustaine switch driver and
energy recovery switch driver in the Plasma Display
Panel application, motor drive inverter, switching power
supply, and high-power DC-DC converter applications.
