DATA SHEET .onsemi. 110 V 2.5 A Single Channel Floating Gate Drivers with Desaturation Protection and Charge Pump FAD3151MXA, FAD3171MXA The FAD3151MXA and FAD3171MXA are single channel floating automotive gate drivers suitable for driving high- speed power MOSFETs up to 110 V. Designed in a SOI technology, the drivers are ideal for applications that require noise immunity against severe negative transients and ground offset up to - 80 V. The FAD3151MXA/71 drivers have an integrated desaturation detection to protect the power switches during short- circuit and over- current conditions. The drivers are 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. The FAD3151MXA/71 drivers are equipped with bidirectional fault reporting pin that can generate a fault output during desat and under- voltage lockout (UVLO) condition. The bidirectional nature of the fault- reporting pin allows the driver to respond to external fault mands, thereby facilitating fault munication across the system. In addition, the FAD3171MXA has an integrated charge pump to support 100% duty cycle operation of high side MOSFETs. In summary, the FAD3151MXA/71 are versatile drivers with Features like desat detection, soft shutdown, fault reporting capability, UVLO protection, and charge pump.
