General Description

NFA31512L72 is an advanced IPM module providing

a fully−featured, high−performance inverter output stage for AC

Induction, BLDC and PMSM motors. These modules integrate

optimized gate drive of the built−in IGBTs to minimize EMI

and losses, while also providing multiple on−module protection

features including under−voltage lockouts, over−current shutdown,

thermal monitoring of drive IC, and fault reporting. The built−in,

high−speed HVIC requires only a single supply voltage and translates

the incoming logic−level gate inputs to the high−voltage, high−current

drive signals required to properly drive the module’s internal IGBTs.

Separate negative IGBT terminals are available for each phase

to support the widest variety of control algorithms.
