NXP Semiconductors recently announced the availability of USB battery charger detection solutions for mobile phones. The ISP1704 and ISP1601 are capable of detecting and differentiating between a dedicated USB charger, USB Host Charger and USB Host when charging a mobile phone battery. The mechanism is in accordance with recently introduced regulations in the form of the USB Implementers Forum (USB-IF) Battery Charging Specification Rev. 1.0.
This technology allows for faster charging, longer battery life and initiates automatically whenever the consumer uses the USB connector in their mobile phone. The ability to provide this information enables the system to intelligently charge a battery by determining the level of charging current that it is able to draw, based on the type of USB connection available.
USB 2.0 specifications required that when a portable device is attached to a USB host or hub, the peak supply capacity was limited to 500 mA. New specs from the USB-IF now permit devices to draw current in excess of the USB 2.0 requirements and call for portable devices to be able to distinguish between a high-current wall charger (up to 1,8 A), a USB host or hub charger (up to 1,5 A), and a standard USB host or hub (up to 500 mA).
The ISP1704 is said to be the world's first high speed USB OTG ULPI transceiver to also offer an integrated battery charger detection function. It can transmit and receive USB data at high-speed (480 Mbps), full-speed (12 Mbps) and low-speed (1,5 Mbps) with very little power consumption.
The ISP1601 is a dedicated USB battery charger detection IC with an ultra small CSP footprint of less than 2 mm².
