Greater Noise Immunity, Less Power
Dissipation for Automotive Applications
Advantages
The FAN7171 (high-current, high-side gate driver IC) and FAN7190 (high-current,
high- and low-side gate driver IC) deliver increased efficiency, higher drive current
and greater noise immunity. These devices are optimized for electric and hybrid
electric DC-DC power conversion, high-voltage auxiliaries, diesel and gasoline
fuel injection, and other high-power MOSFET and IGBT driver applications. The
FAN7171 can drive high-speed, high-side MOSFETs and IGBTs that operate
up to +600V, while the FAN7190 can independently drive high- and low-side
MOSFETs and IGBTs that also operate up to +600V. Both devices are highly
integrated and provide increased functionality, resulting in reduced component
count, bill of material costs and board space.
