Automotive gate driver targets hybrid/EV apps

Automotive gate driver targets hybrid/EV apps

The FAN7171 high-current, high-side gate driver IC and the FAN7190 high-current, high- and low-side gate driver IC target electric and hybrid electric dc/dc power supplies and power inverters, diesel and gasoline injectors and valves as well as MOSFET and IGBT high-side driver applications. The FAN7171 can drive high-speed MOSFETs and IGBTs that operate up to +500 V, while the FAN7190 can drive MOSFETS and IGBTs that operate up to +600 V.

Both driver IC devices have a buffered output stage with all NMOS transistors designed for high-pulse current driving capability and minimum cross-conduction. They have a negative voltage swing (VS) down to –9.8 V at 15 VBS. The driver ICs are qualified to AEC Q100 Automotive Class 1 standards. They have an under voltage lockout circuit that prevents malfunction when VBS is lower than the specified threshold voltage. Both devices are packaged in an 8-lead small outline package (SOP) and are RoHS-compliant. (Ea/1,000: FAN7171, $1.28; FAN7190, $1.50 — available now.)
