Smart Load Switches save PCB space in portable appliances.

Press Release Summary:

Offered in 2 x 2 mm MLF® packages, MIC94066/67/68/69 smart high-side load switches provide up to 2 A continuous current per channel via low on-resistance p-Channel MOSFETs. MIC940xx series, suited for power-sensitive, sub-5 V applications, operate with inputs from 1.8-5.5 V and can be driven by 1.5 V logic. Miniature high-current load switches exhibit low quiescent current (2 µA) and low shutdown current (under 1 µA).

Micrel Adds New ICs to Expanding Family of Smart Load Switches

SAN JOSE, Calif., Sept. 25 -- Micrel Inc. (NASDAQ:MCRL), an industry leader in analog, high bandwidth communications and Ethernet IC solutions, today launched new additions to their 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(R) packages these high output current switches are ideal 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 manufacturers of portable personal appliances," noted John Lee, Micrel's director of Mixed- Signal and RF Products, Micrel. "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 2uA and low shutdown current of less than 1uA, provides ideal solutions for power-sensitive, sub-5V or less applications."

The MIC94066/67/68/69 operate with inputs ranging from 1.8V 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.
