Description
The FAN7391 is a monolithic high- and low-side gate-
drive IC, which can drive high-speed MOSFETs and
IGBTs that operate 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 circum-
stances. An advanced level-shift circuit offers high-side
gate driver operation up to V_S=-9.8 V (typical) for
V_BS=15 V.
The advanced input filter of HIN provides protection
against short-pulsed input signals caused by noise.
The UVLO circuit prevents malfunction when V_DD and
V_BS are lower than the specified threshold voltage.
The high-current and low-output voltage-drop feature
makes this device suitable for the PDP sustain pulse
driver, motor driver, switching mode power supply, and
high-power DC-DC converter applications.
