ON Semiconductor Introduces Fully Integrated Li-Ion Battery Charger to Address Next Generation Power Efficiency Demands

ON Semiconductor (Nasdaq: ONNN) a premier supplier of high performance silicon solutions for energy efficient electronics, has introduced a fully programmable Lithium- Ion (Li-Ion) switching battery charger optimized for power efficiency in smart pho

Mumbai (I-Newswire) August 31, 2012 - With 1.6 ampere (A) charging capability, the device is perfectly sized at 2.2 x 2.55 mm for the latest USB compliant input supplies and large battery capacities and can complete a full charge cycle of a 1650 milliampere hour (mAh), 4.2 volt (V) Li-Ion battery in 90 minutes.

“Robustness, efficiency and fast charge time are now pre-requisites for designers of today’s high performance, ultra-space constrained applications,” said Thibault Kassir, director of ON Semiconductor’s Interface & Power ICs Division. “The NCP1851 single chip solution allows simple integration into the latest USB charging designs. We are already receiving wins from our major customers for the device due to its charge time performance and advanced feature set.”

The NCP1851 integrates dynamic power path management which enables instant system turn-on in case of a weak battery and helps replenish a deeply discharged battery. Both the device’s internal junction temperature sensor and external Negative Temperature Coefficient (NTC) thermistor ensure safe charging of the system by reporting dedicated interrupts to the i²C Control Bus. The NCP1851 provides a USB On-the-Go (OTG) mode that boosts battery voltage to power accessories plugged into the USB port, eliminating the need for another step-up converter.


Packaging and Pricing
The NCP1851 is housed in a 25 bump Flip-Chip CSP package case with overall dimensions of a mere 2.2 mm x 2.55 mm and height of 0.6 mm maximum. The device is priced at USD1.25 per unit in 3,000 quantities.
