Overview: DATA SHEET www.onsemi.com 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 commands, thereby facilitating fault communication across the system. In addition, the FAD3171MXA has an integrated charge pump to support 100% duty cycle operation of high side MOSFETs.
