Power modules cut motor drives down to
size
Modules integrate two HVICs, one LVIC, four NPT IGBTs, four fast recovery diodes, two bootstrap diodes, a thermistor and various protection functions in a single package.
Fairchild Semiconductor has released the industry's first SRM-SPM power modules for driving two-phase switched reluctance motors (SRM) in small motor applications such as vacuum cleaners Switched reluctance motors are an attractive alternative to AC drives due to their high efficiency

Dual-output buffer for DDR SDRAM modules
Fairchild Semiconductor has introduced a dual-output registered buffer for 184-pin, 2.5V PC200/PC266, 72bit-wide registered double data rate (DDR) SDRAM modules.
Bus hold makes logic more predictable
Fairchild Semiconductor has made a number of additions to its LCX family, the logic industry standard for 3.3V applications.
The small motor industry is migrating from single-phase to two-phase SRM motors because of their ability to start under difficult load conditions and the smaller component count that these motors require.
Each of the FCAS20DN60BB and FCAS30DN60BB SRM-SPM modules integrates two HVICs, one LVIC, four NPT IGBTs, four fast recovery diodes (FRDs), two bootstrap diodes, a thermistor and various protection functions in a single package.
By integrating 14 fully tested power components in a compact 45 x 28mm SIL package, these products offer 40% space savings.
This space conservation allows vacuum cleaner designers to incorporate the controller into the SRM assembly, and also improves design productivity and manufacturability.
System reliability is further enhanced by incorporating protection features such as undervoltage lockout and short circuit protection into this thermally efficient package.
"Fairchild continues to provide cutting-edge efficient solutions that innovate today's electronics".
"These SPM power modules for two-phase switched reluctance motors are an example of how Fairchild provides solutions that deliver excellent performance, while minimising design and manufacturing time", says Taehoon Kim, Vice President of Fairchild's Functional Power Solutions.
The FCAS20DN60BB and FCAS30DN60BB have lead-free (Pb-free) terminals and have been characterised for moisture sensitivity in accordance with the Pb-free reflow requirements of the joint IPC/JEDEC standard J-STD-020.
Samples are available now, and 100-piece pricing is US $16.38 for the FCAS20DN60BB (600V/20A) and US $17.94 for the FCAS30DN60BB (600V/30A), with delivery 12 weeks ARO.
