The transaction furthers ISSI's plan to expand its product offerings into one of the fastest-growing segments of the electronics industry, while Signia gains a bigger partner that can help reduce the costs of marketing and manufacturing its products.

The PCF50606 PMU+, to be introduced today, is the company's first integrated power management IC designed specifically for PDAs and smart phones. The device features software controls for dynamic power management, which supports Intel Corp.'s X-Scale processor power management specifications.

Early PDAs typically worked on a single voltage, making power management less of a challenge. Today, features like backlighting, color displays, rechargeable batteries, and wireless communication interfaces are putting higher demands on the system, according to Reinier Van Der Lee, product marketing manager for power management ICs at Philips in Eindhoven, Netherlands.

While integrated solutions have become common in cellular handsets, the majority of PDAs still use discrete solutions. According to Van Der Lee, the PCF50606 is positioned to help steer the industry's transition.

The chip integrates a step-down converter, up/down converter, high-current down converter, five programmable 150mA low-dropout regulators, dynamic voltage management, battery voltage monitor, and main and backup battery chargers in a single 94mm2 package, half the size of a discrete solution, according to Philips.

System features include an 12C interface, 32KHz clock, maskable interrupt controller, watchdog timer, 10-bit A/D converter, touchscreen interface, real-time clock module, pulsewidth modulator, LED modulator, and six general-purpose outputs.

At $5 in 10,000-unit quantities, the device also costs about 25% less than comparable discrete solutions, according to Van Der Lee. The PCF50605, without battery management or touchscreen interface, is offered at $4 in similar quantities. Both Philips chips use a HVQFN56 8 ?? 8 ?? 1mm package.

Samples are available, with production expected in the third quarter, according the company.

Santa Clara, Calif. – The Si8405DB and Si8401DB MOSFETs and DG3000 analog switch from Vishay Siliconix are intended for mobile phone designs. The Si8405DB features a 12-volt breakdown voltage, a 1.8-V gate drive and a 1.6 x 1.6 x 0.65-mm footprint. The Si8401DB is a single p-channel device with a 20-V drain-to-source voltage and a 65-milliohm maximum on-resistance at a gate drive of -4.5 V. The DG3000 analog switch runs from a 1.8-V supply and measures 1.07 x 1.57 x 0.7 mm.

The switch delivers a 5-picocoulomb charge injection specification and can handle frequencies over 100 MHz. In 100,000-unit quantities, the MOSFETs are priced at 36 cents each and the analog switch at 47 cents.

The good news from the survey is that almost all participants said they had or are developing a formal strategy for diversity. Eighty-six percent of the 106 companies who responded said they have a formal strategy at the corporate level. Companies said diversity programs were an integral part of gaining competitive advantage and improving retention, marketing/sales results and recruitment.

I was disappointed, however, when I called to ask about whether the survey investigated the effectiveness of diversity programs. No, the survey was intended as a benchmark for companies to see how they stack up against their peers in offering such programs.

I'd like to know how effective the programs have been, to see if companies have made widespread changes and if those changes have affected the company's balance sheet.

Are diversity programs more than programs, more than lip service to what's become an in” trend? It's time to find out.

Later this year Catalyst plans to report the results of a Women of Color survey that involves re-contacting women who were surveyed in 1999 and finding out where they are in their careers today. Stay tuned.
