High security for smart card MCU family
Philips Semiconductors describes SmartMX as the world's first ultra-low-power cost-optimised high-performance family of smart card controller ICs.
Applications in all segments require load switch functionality for controlling lamps, drivers, chargers, fans and various electrical circuits and power lines.
Traditionally, this function has been carried out by mosfets or bipolar transistors with up to six components.
With the new BISS Loadswitch devices, which require only two external resistors, design engineers have an integrated solution that will reduce component count and also eliminate the need to source several discrete components, saving both cost and time while saving valuable board space.
"Our new BISS Loadswitch devices continue Philips' leadership in offering smart and cost saving solutions for customer applications where space limitations are a concern", said Lars Boysen, International Product Marketing Manager, General Application Discretes at Philips Semiconductors.
"With a footprint of 1.6 x 1.2mm, the BISS Loadswitch devices in SOT666x are ideal for applications such as PDAs, notebooks and mobile phones that have high performance demands but limited board space".
The first Philips BISS Loadswitch devices in SOT666 (15V, 500mA) are suitable for mobile applications.
Future devices for automotive and consumer applications offer up to 1A current handling at 40-80 V in SC-74 packages.
The first three BISS Loadswitch devices are available now in the SOT666 package.
Additional products in this family, in SC-74 and SC-88 packages, will be available in Q2 2004.
