Micrel, Inc. today introduced the MIC1344, a 3A power ORing smart switch offered in a small 2mm x 2mm QFN package. The MIC1344 targets handheld devices and systems powered from multiple sources such as wall adapters and auxiliary battery power sources. It is also suited for applications that require a diode OR function between two input power sources. The MIC1344 is available in volume quantity with 1,000 quantities pricing starting at $2.33.
“The MIC1344 power ORing switch is designed to reduce heat by minimizing voltage drop across the power switch. It saves valuable board space which remains crucial in the design of mobile devices,” noted Brian Hedayati, vice president of marketing for high performance linear and power solutions at Micrel. “To increase design flexibility the device also offers programmable current-limit for each channel, automatic or manual input selection and four status outputs.”
