onsemi FAD31x1MXA Automotive Gate Driver
Designed against severe negative transients and ground offset
The onsemi FAD3151MXA and FAD3171MXA are single channel floating automotive gate drivers suitable for driving high−speed power MOSFETs up to 110V. Designed in an SOI technology, the driver is ideal for applications that require noise immunity against severe negative transients and ground offset up to −80 V.
These gate drivers feature integrated desaturation detection to protect power switches during short−circuit and over−current conditions. The 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.
The FAD3151MXA and FAD3171MXA drivers are equipped with bidirectional fault reporting pin that can generate a fault output during desaturation 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.
The FAD3171MXA adds an integrated charge pump to support 100% duty cyle operation of high side MOSFETs.
The two gate drivers can be used together.
