ON Semiconductor releases new full bridge rectifier for portable products

NMLU1210 will minimise conduction losses and increase efficiency of the charging system

By CBR Staff Writer

Silicon applications firm ON Semiconductor has released a new power MOSFET IC for wireless charging applications in portable products.

Known as NMLU1210, it is a 20 volt (V) N-channel full bridge semi-synchronous rectifier.

The new application will minimise conduction losses and increase efficiency of the charging system by incorporating dual Schottky barrier diode supporting up to 3.2 ampere (A) operation plus two MOSFETs with a 17 milli ohm (m?).

The receiver side uses NMLU1210 to convert AC voltage generated by the transmitter to DC voltage used for battery charging.

The new IC is offered in a low inductance thermal efficient package and is optimised for power management tasks in portable electronic products.

ON Semiconductor Power MOSFET products division vice-president Paul Leonard said the NMLU1210 full bridge rectifier enables efficient and fast wireless charging of portable electronics devices.

"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," said Leonard.
