Micrel Adds New ICs To Expanding Family of Smart Load Switches

September 26, 2006 by Jeff Shepard

Micrel Inc. launched new additions to its family of miniature high current load switches. The MIC94066/67/68/69 are all part of a family of smart high-side load switches. Housed in tiny 2mm x 2mm MLF®, packages these high output current switches are well-suited for portable applications such as cellular phones, PDAs, MP3 players, digital cameras, notebook PCs, barcode scanners, battery switch-over circuits and level translator applications. The ICs are currently available in volume, with pricing starting at $0.56 for 10K quantities.

"Battery life continues to be of paramount concern to manufactures of portable personal appliances," noted John Lee, Micrel's Director of Mixed-Signal and RF Products. "Switching subsystem power on and off as user demands change has become a common strategy for extending battery life. The new MIC940xx series, with its low quiescent current of 2µA and low shutdown current of less than 1µA, provides ideal solutions for power-sensitive, sub-5V or less applications."

The MIC94066/67/68/69 operate with inputs ranging from 1.8 to 5.5V and can be driven by 1.5V logic. They provide up to 2A of continuous current per channel via low on-resistance p-Channel MOSFETs with 2A of continuous current. PC board space is saved in portable applications with Micrel's low thermal resistance 2mm x 2mm package.
