SANTA CLARA, Calif.,
June 28, 2011 /PRNewswire/ --
Advanced Analogic Technologies, Inc. (AnalogicTech™) (Nasdaq:
AATI), an analog semiconductor company focused on powering
innovative solutions in consumer, industrial, and communications
markets, today introduced the AAT4616 SmartSwitch™ family of fully
adjustable, low RDS(ON), ultra-high precision current limited
P-channel MOSFET power switches designed for high side load
switching applications. Offering precision-current-limit capability
as tight as +/- five percent, the AAT4616 family allows system
designers to reduce the margin they would otherwise typically have
to implement in their systems. This allows products such as HDTVs,
set top boxes and tablet computers to maximize the power usage from
their USB or other supply rails and buses.

"In previous generations of our Load Switch Family, we
integrated many discrete functions into space saving, single-chip
solutions," said Roger Smullen,
Director of Strategic Marketing for AnalogicTech. "With the
introduction of the AAT4616 family, we deliver the same high
performance, fully integrated solution with the added benefit of
ultra-high precision current limiting. Whether our customers are
producing HDTVs, tablets, set top boxes or 3G/4G USB datacards,
they must constantly improve the performance, cost, size and
efficiency of their products, and the AAT4616 products help them
achieve those goals."
The AAT4616 family broadens the AnalogicTech Integrated Load
Switch family by adding the ultra-high precision (+/- five percent)
AAT4616 and the high precision (+/-10 percent) AAT4616A to the
existing family of current limit devices. System designers can also
pick from a broad set of options to select the best device for
their end product, including: active hi/lo enable, fault flag/no
fault flag, resistor settable current limit, precision, and
multiple package choices, among others. The comprehensive options
and benefits available from the AAT4616 family deliver maximum
flexibility to meet a full range of product design
requirements.
Further, the AAT4616 family incorporates a host of protection
features including reverse blocking, over temperature shutdown,
short circuit protection and fast transient response to ensure safe
system operation. Finally, the SOT23-5 versions of the AAT4616
family are pin compatible with the previous generation AAT4610 and
AAT4614 parts, which facilitates upgrading an existing end product
to a higher performance current limit IC with a drop-in
replacement.
The AAT4616 family is priced from US$0.54
to US$0.61 @10K units, depending on part and features. For
other quantities, contact AnalogicTech or its distributors. The
AAT4616 and AAT4616A are currently shipping.
