AnalogicTech Announces First ModularBCD 12V Slew Rate Controlled Load Switch
SUNNYVALE, Calif., April 25 /- Advanced Analogic Technologies Incorporated (AnalogicTech) (NASDAQ:AATI), a developer of power management semiconductors for mobile consumer electronic devices, announced today the AAT4285, the industry's first integrated slew-rate controlled load switch capable of supporting 12-V operation. By integrating level shift and slew rate control functionality into a single device, the AAT4285 allows designers to reduce power consumption and minimize parts count in a wide range of new 12-V applications in portable consumer as well as non-portable industrial systems.
"Until now our extensive line of slew rate controlled load switches have been widely used to replace discrete solutions in a variety of portable systems running off a 5V supply," said Phil Dewsbury, product line director for AnalogicTech. "By offering the same functionality for 12-V operation, the AAT4285 allows designers for the first time to eliminate a discrete MOSFET and up to 11 external components in both higher powered portable systems such as test equipment or camcorders as well as a wide range of non-portable industrial applications."
Fast Load Switch Time
The AAT4285 is a P-channel MOSFET switch designed for high-side load switching applications. The device operates across a 3.0-V to 13.2-V input range. Functionally compatible with AnalogicTech's AAT4250 and AAT4280 products, the AAT4285 offers a fast load switch turn-on time of 100 µs. A fast shutdown load discharge capability allows the device to quickly turn off a load circuit when the switch is disabled.
The AAT4285 also offers a very low RDS(ON) of 240 milliohms typical @ 12V to maximize load switch power handling capability. At 5V, RDS(ON) is 320 milliohms typical. Quiescent current is 25 uA typical.
New Process
The AAT4285 is the first 12-V device manufactured in AnalogicTech's ModularBCD process technology. Unlike aging linear-IC legacy fabs or generic digital CMOS foundries, the ModularBCD process represents the first of a new generation of analog, power and mixed-signal IC technologies especially created for high-tech wafer fabrication and optimized for manufacture in ex- DRAM fabs.
The new process makes single-chip, mixed-signal and system ICs both more technically and economically feasible by monolithically integrating fully- isolated CMOS at 3V, 5V, and 12V with high-speed complementary bipolar transistors and robust 30V DMOS power devices without resorting to highly complex and expensive techniques such as epitaxy or high-temperature diffusion. As a result, devices manufactured in ModularBCD offer higher efficiency, smaller size, and higher levels of integration than devices fabricated in traditional processes, and can better manage power and extend battery life in a wide range of mobile consumer electronics products such as cell phones, portable media players, tablet and laptop computers and digital cameras.
Price and availability
Specified across the -40 degrees to +85 degrees C temperature range, the AAT4285 is available in a Pb-free, 8-pin SC70JW package. It sells for $0.68 in 1,000 piece quantities.
