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.
In summary, the FAD3151MXA/71 are versatile drivers with
features like desat detection, soft shutdown, fault reporting capability,
UVLO protection, and charge pump.
