ON Semiconductor has introduced the NUS3116, an integrated charging and power switching circuit for small form factor portable electronics. This circuit combines a main battery switch, wall charging switch and USB charging switch elements into a single component, optimising charging performance and saving critical space on circuit boards.
The NUS3116 is an integration of main power switch, -12 V,
-6,2 A 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 40 mΩ maximum RDS(ON), the main switch MOSFET minimises power loss during battery operation of portable electronics. The dual low-Vce(sat) transistors provide good thermal performance for charge currents up to 2 A, and have a Vce voltage drop of less than 240 mV at the end of the charging.
