General Description

module providing a fully-featured, high-performance

inverter output stage for AC Induction, BLDC and PMSM

motors. These modules integrate optimized gate drive of

EMI and losses, while also providing multiple on-module

protection features including under-voltage lockouts and

thermal

monitoring.

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

MOSFETs.

Separate open-source MOSFET terminals are available

for each phase to support the widest variety of control

algorithms.
