General Description
FSB50450T is a tiny smart power module (SPM
FRFET technology as a compact inverter solution for small
power motor drive applications such as fan motors and water
suppliers. It is composed of 6 fast-recovery MOSFET (FRFET),
and 3 half-bridge HVICs for FRFET gate driving. FSB50450T
provides low electromagnetic interference (EMI) characteristics
with optimized switching speed. Moreover, since it employs
FRFET as a power switch, it has much better ruggedness and
larger safe operation area (SOA) than that of an IGBT-based
power module or one-chip solution. The package is optimized
for the thermal performance and compactness for the use in the
built-in motor application and any other application where the
assembly space is concerned. FSB50450T is the most solution
for the compact inverter providing the energy efficiency,
compactness, and low electromagnetic interference.
