FSBM20SL60

General Description

FSBM20SL60 is an advanced smart power module (SPM)

that Fairchild has newly developed and designed to provide

very compact and high performance ac motor drives mainly

targeting low speed low-power inverter-driven application

like air conditioners. It combines optimized circuit protection

and drive matched to low-loss IGBTs. Highly effective

short-circuit current detection/protection is realized through

the use of advanced current sensing IGBT chips that allow

continuous monitoring of the IGBTs current. System

reliability is further enhanced by the integrated under-

voltage lock-out protection. The high speed built-in HVIC

provides opto-coupler-less IGBT gate driving capability that

further reduce the overall size of the inverter system design.

In addition the incorporated HVIC facilitates the use of

single-supply drive topology enabling the FSBM20SL60 to

be driven by only one drive supply voltage without negative

bias. Inverter current sensing application can be achieved

due to the divided negative dc terminals.

Features

• UL Certified No. E209204

• 600V-20A 3-phase IGBT inverter bridge including control

ICs for gate driving and protection

• Divided negative dc-link terminals for inverter current

sensing applications
