General Description

The FSB50550B / FSB50550BS is an advanced Motion

performance inverter output stage for AC Induction,

BLDC

and

PMSM

motors.

These

modules

integrate optimized gate drive of the built-in MOSFETs

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.
