General Description  
3 divided negative dc-link terminals for inverter current sens-  
ing applications  
FSB50550AB 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. FSB50550AB  
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. FSB50550AB is the best  
solution for the compact inverter providing the energy efficiency,  
compactness, and low electromagnetic interference.

3. The voltage drop across R
 
affects the low side switching performance and the bootstrap characteristics since it is placed between COM and the source terminal of the low side

MOSFE
T
. For this reason, the voltage drop across R
 
should be less than 1V in the steady-state.

4. Ground wires and output terminals, should be thick and short in order to avoid surge voltage and malfunction of HVIC.  
®
5. All the filter capacitors shoud be connected close to SPM
 
, and they should have good characteristics for rejecting high-frequency ripple current.

LIFE SUPPORT POLICY  
FAIRCHILD’S PRODUCTS ARE NOT AUTHORIZED FOR USE AS CRITICAL COMPONENTS IN LIFE SUPPORT DEVICES OR SYSTEMS WITHOUT THE  
EXPRESS WRITTEN APPROVAL OF FAIRCHILD SEMICONDUCTOR CORPORATION.  
As used herein:  
1. Life
 
support devices or systems are devices or systems which, (a) are  
intended for surgical implant into the body or (b) support or sustain life,  
and (c) whose failure to perform when properly used in accordance with  
instructions for use provided in the labeling, can be reasonably  
expected to result in a significant injury of the user.  
2. A
 
critical component in any component of a life support, device, or  
system whose failure to perform can be reasonably expected to cause  
the failure of the life support device or system, or to affect its safety or  
effectiveness.  
ANTI-COUNTERFEITING POLICY  
Fairchild Semiconductor Corporation’s Anti-Counterfeiting Policy. Fairchild’s Anti-Counterfeiting Policy is also stated on our external website,  
Counterfeiting of semiconductor parts is a growing problem in the industry. All manufactures of semiconductor products are experiencing counterfeiting of their  
parts. Customers who inadvertently purchase counterfeit parts experience many problems such as loss of brand reputation, substandard performance, failed  
application, and increased cost of production and manufacturing delays. Fairchild is taking strong measures to protect ourselves and our customers from the  
proliferation of counterfeit parts. Fairchild strongly encourages customers to purchase Fairchild parts either directly from Fairchild or from Authorized Fairchild  
Distributors who are listed by country on our web page cited above. Products customers buy either from fairchild directly or from Authorized Fairchild  
Distributors are genuine parts, have full traceability, meet Fairchild’s quality standards for handing and storage and provide access to Fairchild’s full range of  
up-to-date technical and product information. Fairchild and our Authorized Distributors will stand behind all warranties and will appropriately address and  
warranty issues that may arise. Fairchild will not provide any warranty coverage or other assistance for parts bought from Unauthorized Sources. Fairchild is  
committed to combat this global problem and encourage our customers to do their part in stopping this practice by buying direct or from authorized distributors.
