IRVINE, Calif., Nov. 14, 2006 (PRIMEZONE) -- Microsemi Corporation (Nasdaq:MSCC), a leading manufacturer of high performance analog/mixed signal integrated circuits, has announced two new advanced-feature Lithium-Ion/Lithium Polymer battery charger circuits for use in MP3 jukeboxes, personal media centers, digital cameras, PDA phones and other portable applications.
-- Ideal for single cell LiIon applications in small spaces -- Programmable charge current levels for USB and wall adapters -- Precision tolerances ensure safe charging -- Low current sleep mode minimizes battery drain
Designated the LX2205(tm) and LX2206(tm), the new chargers expand Microsemi's portfolio of highly integrated battery charging circuits featuring separate wall adapter and USB power interfaces. Their dedicated USB charger interfaces force charging current to remain below USB limitations.
"We design Microsemi battery chargers to simplify the control of battery charging and to provide the thermal control that's needed for faster high current charging," said Paul Bibeau, Sr. Vice President and General Manager of Microsemi's Integrated Products Group.
Both chargers feature a pre-charge conditioning mode for batteries that have been deeply discharged, two-step constant current -- constant voltage charging and a top-off charge mode for batteries that are left on a charger for extended periods. An integrated power FET minimizes the need for external components, making it ideal for space critical applications.
The LX2205, which provides a maximum charge current of 1 amp for batteries rated at up to 2 amp hours, is packaged in a 4 millimeter square MLP surface mount package. Its isolated battery topology permits portable devices to operate from wall outlets when batteries are missing or shorted. It also allows automatic balancing of the charge current between the device load and charging of the battery. It includes two LED drivers for indicator lights and is priced at $0.75 in 10K quantities.
The LX2206 provides a maximum charge current of 1 amp for batteries rated from 50 mili-amps to 2 amp hours and is packaged in a space-saving 3 millimeter square MLP surface mount package. It includes three LED drivers and is priced at $0.45 in 10K quantities.
