San Jose, Calif. - Royal Philips Electronics' BISS Loadswitch devices combine their low VCE(sat) (BISS) transistors with so-called resistor-equipped transistors (RETs) to offer load switch functionality in a SOT666 package, cutting board space requirements by almost half. An alternative to MOSFETs or bipolar transistors requiring up to six components, the BISS Loadswitch, part of the company's PBLS series, requires only two external resistors for controlling lamps, drivers, chargers, and fans.
"With a footprint of 1.6 by 1.2 mm, the BISS Loadswitch devices in the SOT666x are ideal for applications such as
PDAs, notebooks and mobile phones that have high performance demands but limited board space," says Lars Boysen, international product marketing manager for general application discretes.
The first of the BISS Loadswitch devices in this family (15 V, 500 mA) are suitable for mobile applications. Future devices for automotive and consumer applications
will offer up to 1 amp at 40 to 80 volts in a SC-74.
The new loadswitch devices (3 versions) are available now and priced from 0.8 to 5 cents each, depending on type and quantity. Other loadswitch devices in SC-74 and SC-88 packages will be available in Q2.
