Li-Ion battery charger targets next generation power efficiency demands
August 29, 2012 // Paul Buckley
ON Semiconductor has introduced a fully programmable Lithium-Ion (Li-Ion) switching battery charger optimized for power efficiency in smart phones, tablets and other handheld devices. The NCP1851 reduces charge time, increases battery life and includes advanced startup features.
With 1.6 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 mAh, 4.2 V Li-Ion battery in 90 minutes.
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 $1.25 per unit in 3,000 quantities.
