Dual-port Gigabit Ethernet transceiver
National Semiconductor has announced the DP83862, a low-cost, highly integrated dual-port 10/100/1000 physical layer transceiver.
World's smallest multifunction supervisory ICs
National Semiconductor has announced a family of supervisory ICs with a variety of factory-programmable features that can be configured in hundreds of possible combinations.
The 42V standard will enable carmakers to replace mechanical and hydraulic systems with electrical systems to create cars that are lighter, more reliable and produce fewer emissions.
National's LM2936HV is designed for use in new automotive applications such as integrated starter/alternator, electronic 'drive-by-wire' steering, advanced braking, and other cutting-edge technologies that are expected to begin hitting the market with the 2005 model year.
"National's new LM2936HV continues our longstanding support of the automotive market while meeting automakers' needs for high-voltage semiconductors that are key to delivering the next generation of automotive solutions", said Thomas Eikenberg, product marketing manager, enhanced solutions group Europe.
"Our focus is to bring standard products, such as the LM2936HV, to the market which supports today's needs as well as automakers future plans for cars that are safer, cleaner, and more fuel efficient".
Designed to meet the needs of tomorrow's high-voltage automotive applications, the LM2936HV supports continuous input voltages up to 60V with a 50mA output.
It features an ultra-low quiescent current (9uA, typical) that is ideal for sleep mode and other 'keep alive' applications that demand constant power without placing excessive drain on the battery.
The LM2936HV is available today in the small outline integrated circuit (SOIC) package and a 5V output.
Variations of the product at 3 and 3.3V will be available shortly.
Also coming are an on-off pin with an operating range from 2 to 60V for "standby" applications and power packages for enhanced heat dissipation.
The LM2936HV is priced at $0.86 each in quantities of 1000.
