MOSFETs to give that home theatre sound
Zetex has launched a series of four N- and P-channel MOSFETs providing all the performance demanded by Class D audio systems.
Chip takes control of brushless fans and blowers
The ZXBM2000 series of controller ICs offers a complete variable speed control solution for two-phase, DC brushless fan and blower motors up to 100W.
Aimed at general low to medium voltage switching applications, the Generation 5 bipolars will meet the demands of a wide range of applications including battery charging, motor control, FET driving and resonant converters.
Generation 5 technology will optimise the performance of existing Zetex large area die types and offer improved efficiency and power levels and in some instances, a reduction in PCB space requirements.
Ten Generation 5 transistors are initially planned, covering a voltage range from 20 to 140V.
Package types will include SOT89, "large flag" SOT23 and SOT223.
The range of SOT223 devices will include four NPN transistors (25-100V, Ic up to 7A) and four PNP transistors (30-140V, Ic up to 5.5A).
Zetex' Power Management Group Manager Jos Van Loo said: "Our Generation 5 products demonstrate once more the tremendous advantage bipolar technology still holds over mosfet technology in many low to medium voltage applications.
This is just one more stage in an exciting product road map that promises a very bright future for bipolars".
He continued: "Our future benchmark developments include a Generation 6 platform, currently in progress and a Generation 7 platform, which is at the feasibility stage.
Both platforms aim to further increase bipolar capabilities through a combination of innovative die processing and optimised packaging techniques".
