Integrated Charging and Power Switching Circuit

( 1 Nov 2007 )

ON Semiconductor introduces the NUS 3116, an integrated charging and power switching circuit for small form factor portable electronics like cellular phones. This circuit combines a main battery switch, wall charging switch, and USB charging switch elements into a single component, optimizing charging performance and saving critical space on circuit boards in handheld electronic devices.

The NUS3116 is an integration of main power switch, -12V, -6.2A, µCool single P-channel MOSFET to handle the main battery switch function and two internal low saturation PNP transistors to handle dual channel charging elements. With 40m¦¸ maximum RDS (ON), the main switch MOSFET minimizes power loss during battery operation of portable electronics.
