11/24/2003 - Royal Philips Electronics (NYSE: PHG, AEX: PHI) has expanded its ÁTrenchMOS family with a number of low on resistance RDS(ON) MOSFETs ideally suited for use in wireless communication, mobile computing and consumer multimedia applications. These new P-channel devices provide designers of space-constrained applications high performance power control in a range of ultra-compact and industry-standard packaging. The first P-channel MOSFET is the 20V 50 milli ohm PMN50XP in a 2.9mm X 1.5mm TSOP6 package, which gives designers an excellent choice for cost-effective power management in a very small package.
In mobile handsets alone, more than one billion P-channel devices will be used each year as the number of handset shipments is expected to increase from 480 million in 2003 to 640 million in 2007, according to iSuppli. With the proliferation of mobile applications, including notebook PCs and handheld consumer devices, there is an ever-increasing demand for compact and efficient power management solutions. Philips' P channel devices meet this need by offering cost-effective power management devices that help designers conserve board space, increase energy efficiency and prolong battery life.
"These new P-Channel devices together with the n channel ÁTrenchMOS devices released earlier this year encompass a broad range of complimentary power management products to meet our customer requirements for the growing number of 'on the move' applications in mobile computing and mobile handsets," said Manuel Frade, vice president and general manager of Philips Semiconductors' Power Management Business Line. "These devices are ideal for any consumer application requiring high MOSFET performance where board space and energy efficiency are critical design factors."
P channel MOSFETS are used in load and battery switching applications in a variety of portable applications. Modern power management systems are often required to switch one or more power supply lines according to the specific requirements of the system at any given time. For example in a notebook PC, the power to the display and disc drive is turned off during "sleep" states in order to conserve battery power. The power switches employed in such systems must exhibit low voltage drop in the "on" state, be easy to drive and occupy as small a PCB area as possible. In addition, the power switches must be capable of "floating" operation, where neither of the main current carrying terminals is connected to 0V. The low on-resistance RDS(ON) of power MOSFETs make them the obvious choice in such applications, with P-channel versions being particularly easy to drive in "floating" applications. P channel devices are also increasingly being used in complementary configurations with N channel devices in LCD monitors and point-of-load applications.
Philips is expanding its range of p-channel MOSFETs in industry standard packages with additional products available in the next few months. Philips' P channel devices are typically 50mOhm at 4.5V and rated for 2.5V gate drive. The new range of MOSFETs includes devices with both 20V and 30V VDS ratings, and drive characteristics which mean the devices are fully turned on with gate drive voltages as low as 2.5V.
Pricing and Availability
Samples of Philips' P channel products are currently available in the TSOP6 package. Philips will expand its P channel range to include a variety of devices and packages - from the tiny SC89 to high power LFPak package.
