Description

The FAN7191 / FAD7191 is a monolithic high− and low−side

gate−driver 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 driving capability and minimum

cross−conduction.

ON Semiconductor’s high−voltage process and common−mode

noise canceling technique provide stable operation of high−drivers

under high dV/dt noise circumstances. An advanced level−shift circuit

allows high−side gate driver operation up to VS = −9.8 V (typical) for

VBS = 15 V.

The UVLO circuit prevents malfunction when VDD and VBS are

lower than the specified threshold voltage.

The high current and low output voltage drop features make this

device suitable for controlling direct injection actuators and for use in

many automotive DC−DC converter and motor control applications.
