| Micrel Announces New Family of High-Current Power Distribution Switches | |||||
San Jose, Calif. - Micrel Inc. launched a family of high-current power switches. The MIC2004/5/6 chips are aimed at PCs, Set-Top-Boxes, Game controllers and USB host devices, including the market’s latest printers which all require current limiting as protection against short circuits. The MIC2004, MIC2005 and MIC2006 are currently available in volume quantities and in two package options, SOT-23 and 2mm x 2mm MLF™. Pricing starts at $0.54 in 1K quantity for SOT-23 and $0.58 in 1K quantity for MLF. “The consumer market, especially for multi-function printers, continues to be robust,” noted Scott Brown, director of Mixed-Signal and RF Products, Micrel. “All PCs and millions of printers feature USB sockets as the standard connection for peripherals and each requires current limiting as protection against short circuits. Micrel’s newest family of power distribution switches offers the industry’s highest current rating to footprint ratio and an unparalleled feature set, making them ideal for these applications.” The MIC2004/5/6 all feature preset current limits of 0.5A, 0.8A and 1.2A in the smallest form factors available on the market today. These single output ICs are capable of serving multiple (USB) ports providing both cost and space savings. Standard Features include Soft-start turn-ON, thermal protection and an Enable input for eternal switch control. The MIC2004 offers a Load Discharge FET to insure output capacitors retain no charge when the switch is OFF. The MIC2005 features user-adjustable soft-start to create glitch free turn-ON for power supplies ranging from strong to delicate, and a Fault flag for indication of over-current or over-temperature events with fault blanking to prevent nuisance alerts on transient. The MIC2006 offers Dynamic Load Management (DLM), a revolutionary new feature that provides a dynamic current limit in addition to the factory pre-set limit. DLM monitors the source supply for weaknesses and will disable its load if the source voltage drops below a user-defined threshold. This creates a moving current limit which dynamically adjusts itself according to system-wide conditions. “Micrel’s mixed-signal IC solutions continue to stay one step ahead of the market’s needs,” noted Bob Whelton, executive vice president of Operations, Micrel. “The MIC2004/5/6 all offer an innovative feature set, high current ratings and packaging options giving designers the design flexibility and increased functionality they require for space constrained, cost conscious consumer products.” | |||||
