ON Semiconductor Unveils Integrated Charging, Power Switching Circuit

ON Semiconductor (Nasdaq: ONNN), a global supplier of efficient power management solutions, introduced the NUS3116, 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, -12 volt (V), -6.2 amps (A), µCool(TM) 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 mili ohm maximum RDS(ON), the main switch MOSFET minimizes 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 mili volts (mV) at the end of the charging.

Offered in a DFN-8 package that requires only 9 mm2 of board space, the NUS3116 provides a board savings of more than 20 mm2 versus typical solutions using three TSOP-6 packages with interconnect space. The package’s low profile of 0.8 mm allows the device to be used in small form factor designs. Use of the NUS3116 integrated device also reduces the complexity of circuit board layout.

The NUS3116 is available in a Pb-free DFN-8 package, and is priced at $0.80 per unit in 3000 unit quantities.
