FSBB15CH60BT Smart Power Module
July 2007
FSBB15CH60BT
Smart Power Module
Features
• UL Certified No.E209204(SPM27-CC package)
• Very low thermal resistance due to using DBC
• Easy PCB layout due to built in bootstrap diode
• 600V-15A 3-phase IGBT inverter bridge including control ICs
for gate driving and protection
• Divided negative dc-link terminals for inverter current sensing
applications
• Single-grounded power supply due to built-in HVIC
• Isolation rating of 2500Vrms/min.
Motion-SPM
General Description
TM
It is an advanced motion-smart power module (Motion-SPM
TM
)
that Fairchild has newly developed and designed to provide
very compact and high performance ac motor drives mainly tar-
geting low-power inverter-driven application like air conditioner
and washing machine. It combines optimized circuit protection
and drive matched to low-loss IGBTs. System reliability is fur-
ther enhanced by the integrated under-voltage lock-out and
short-circuit protection. The high speed built-in HVIC provides
opto-coupler-less single-supply IGBT gate driving capability that
further reduce the overall size of the inverter system design.
Each phase current of inverter can be monitored separately due
to the divided negative dc terminals.
Applications
• AC 100V ~ 253V three-phase inverter drive for small power
ac motor drives
• Home appliances applications like air conditioner and wash-
ing machine
