FSB50550U
Smart Power Module (SPM®)
Features
• 500V RDS(on)=1.4Ω(max) 3-phase FRFET inverter including
high voltage integrated circuit (HVIC)
• 3 divided negative dc-link terminals for inverter current sens-
ing applications
• HVIC for gate driving and undervoltage protection
• 3/5V CMOS/TTL compatible, active-high interface
• Optimized for low electromagnetic interference
• Isolation voltage rating of 1500Vrms for 1min.
General Description
FSB50550U is a tiny smart power module (SPM®) based on
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. FSB50550U
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. FSB50550U is the most solution
for the compact inverter providing the energy efficiency,
compactness, and low electromagnetic interference.
