Small flash LED driver for mobile handsets
California Micro Devices has unveiled a new family of PhotonIC white LED drivers capable of supporting a wide range of high current flash LEDs in today's most advanced handsets.
The Picoguard XP architecture is a double-clamping architecture that integrates multiple stages of ESD protection into a single device.
This architecture provides robust protection for sensitive high-speed ICs by significantly reducing the clamping voltage and the amount of residual current that passes through to the protected ASIC, achieving significantly better performance than the best ESD diode arrays on the market.
As silicon manufacturing geometries shrink, integrated circuits are becoming increasingly susceptible to ESD damage.

Range cuts the cost of inductor-capacitor filters
LC filters allow mobile handset designers to address many higher bandwidth data interfaces that cannot be served by lower cost resistor-capacitor based devices.
Traditional ESD protection architectures including single-stage, dual-rail clamp diode arrays are no longer adequate to protect the latest system ICs.
The voltage and residual current levels that pass through them will cause gate oxide failures and junction burnout for system ICs designed in the latest silicon processes.
CMD has developed the XtremeESD family of devices, including the new PicoGuard XP, to address these new requirements.
"The critical factor in improving ESD protection is reducing the residual current and clamping voltage seen by the system IC during an ESD strike", stated Joe Salvador, Director of Marketing for Digital Consumer and Computing Products at California Micro Devices.
"CMD's newly developed PicoGuard XP architecture significantly reduces both the residual current and the clamping voltage, while simultaneously preserving the signal integrity of high-speed data".
"It is a suitable solution for protecting sensitive USB, HDMI and DisplayPort data interfaces".
The PicoGuard XP architecture uses a dual-stage design that places two ESD devices and a resistor in series within the same package.
The first ESD circuit absorbs the largest portion of the strike, while the second provides additional clamping and a secondary shunt path to steer current away from the system IC being protected.
The CM1231 provides dramatic improvements compared to the best protection devices currently available including: a 40% reduction in peak clamping voltage; a 40% reduction in peak residual current; and a greater than 65% reduction in total power reaching the ASIC.
A new website provides relevant information about ESD protection to designers of personal computer and digital consumer electronics applications who want to design more reliable systems by understanding the real issues involved in ESD protection and learn about new ESD architectures such as PicoGuard XP.
The site contains technical white papers, product specifications, articles and presentations on various ESD protection topics.
