ON Semiconductor launches the NCP1851 fully programmable Li-ion switching battery charger. Designed for smart phones, tablets and other handheld devices, the device is said to shorten charge time, lengthen battery life and include advanced start-up features.


Tipping 1.6A charging capability, the device completes a full charge cycle of a 1,650mAh 4.2V Li-ion battery in 90 minutes. It integrates dynamic power path management for instant system turn-on in case of a weak battery, and helps replenish a deeply discharged battery. And to ensure safety, it has an internal junction temperature sensor as well as an external negative temperature coefficient thermistor that report dedicated interrupts to the I�C control bus.

The 2.2mm x 2.55mm x 0.6mm charger provides a USB On-the-Go (OTG) mode that boosts battery voltage to power accessories plugged into the USB port without the need for another step-up converter.

The NCP1851 comes in a 25 bump flip-chip CSP package at Rs.68.31 ($1.25) per unit in 3,000 quantities.
