FAD3171MXA

FAD3171MXA is a single channel floating automotive gate driver suitable for driving high-speed power MOSFETs up to 110V. Designed in a SOI technology, this driver is ideal for applications that require noise immunity against severe negative transients and ground offset up to -80V. The FAD3171MXA driver has integrated desaturation detection to protect power switches during short-circuit and over-current conditions. This driver is also equipped with a soft shutdown feature, which initiates a soft shutdown of driver outputs upon desat detection, thus preventing possible overvoltage across power MOSFETs during a heavy-load condition. Applications include gate driver for 80V and 100V MOSFETs, 48V belt starter generator, 48V auxiliary motor control (A/C compressor, e-turbo), 48V battery switches, 48V DC−DC converter, PTC heater, active discharge circuit etc.
