20 March 2012 ON Semiconductor: Rectifier sets new performance levels ON Semiconductor has released an innovative power mosfet ic for wireless charging applications in portable products. Targeting devices such as cell phones, media tablets, portable media players and GPS units, the NMLU1210 is a 20V N-channel full bridge semi-synchronous rectifier. It incorporates a dual Schottky barrier diode supporting up to 3.2A operation plus two mosfets with a 17m? (typical) Rds(ON) designed to minimise conduction losses and increase efficiency of the charging system. Wireless inductive charging works on the principle of an electromagnetic field being created for the rapid transfer of energy between the transmitter (in the charging station) and the receiver (in the portable device). According to ON, the NMLU1210 is used by the receiver side to convert ac voltage generated by the transmitter to dc voltage used for battery charging. The device has been optimised specifically for power management tasks in portable electronic products and, says ON, is suitable for use in space constrained environments. It has an operational junction temperature of -55 to 125°C. "The NMLU1210 full bridge rectifier enables more efficient and faster wireless charging of portable electronics devices," said Paul Leonard, vice president of ON Semiconductor's Power MOSFET products division. "This innovative device will enable OEMs to offer their customers more flexibility in battery recharging which will give their products improved power features in an increasingly competitive consumer space." "ON Semiconductor is an important member of the Wireless Power Consortium," added Menno Treffers, chairman of the Wireless Power Consortium. "The addition of NMLU210 to ON Semiconductor's extensive product portfolio gives the industry more choice and makes it possible to apply the Qi wireless power standard in far more applications and products " Author Chris Shaw Comment on this article Websites http://www.onsemi.com Companies ON Semiconductor This material is protected by Findlay Media copyright See Terms and Conditions.
