Advanced Analogic Technologies Introduces Lowest-Power Load Switch Available for Biometric Security Devices
Date:9/21/2009

SANTA CLARA, Calif., Sept. 8 /PRNewswire-FirstCall/ -- Advanced Analogic Technologies, Inc. (Nasdaq: AATI), an analog semiconductor company focused on powering innovative solutions in consumer, industrial, and telecom markets, introduced the AAT4702, a highly integrated load switch that requires half the board footprint of discrete alternatives. In addition to its small size, the AAT4702 consumes a 15 micro-A quiescent current, far less than any other integrated load switch/low-dropout (LDO) regulator on the market.

Packaged in a compact 8-pin, 2x2-mm FTDFN package, the AAT4702 is a current-limited P-channel metal-oxide-semiconductor field-effect transistor (MOSFET) power switch with an integrated LDO regulator that offers a variety of protection features including auto restart, reverse current blocking and a fault flag to deliver the highest available level of load current protection in a load switch.

"A growing number of applications, such as fingerprint sensing circuits, require both a system power supply and load current protection. The AAT4702 does both," said CJ Zhang, product line vice president. "By integrating a current limited load switch and an LDO in a single compact IC that requires minimal power resources, our new load switch gives notebook and mobile device designers an opportunity to support these applications in a much smaller, lower po
