ICs & Semiconductors * New Products Alpha and Omega Semiconductor Expands the AlphaDFN Portfolio with Low On-Resistance Battery Protection Device Alpha and Omega Semiconductor Limited (AOS) has released the AOC3864, a common-drain 20 V dual n-channel MOSFET with an ultra-low on-resistance of 5.7 mOhms at 4.5 V. This device is designed with a standardized pin-out layout of CSP products with the added mechanical robustness of AOS's patented AlphaDFN packaging technology. This device joins the AlphaDFN family in targeting applications such as the latest smart phones, tables, media players and wearable devices. The growing demand on more data processing capabilities and longer operating time of current smart phones is driving the lithium battery toward another stage of higher capacity. At the same time, innovation in battery cell and charging technology is allowing higher charging current to power-up batteries much faster. As an essential device for battery safety design, MOSFETs with ultra-low onresistance and small form factors are in high demand by smart phone designers. Using AOS's silicon technology, the AOC3864 is able to achieve a 5.7 mOhm at 4.5 V maximum source-to-source resistance within an ultra-thin 2.7 mm by 1.8 mm by 0.19 mm package. All while providing a robust structure to solve die chipping, cracking and placement issues associated with standard CSP products. Lattice's Flexible Charging Controller Supports Qualcomm Quick Charge Lattice Semiconductor Corp. has announced the flexible charging controller family, the LIF-UC family, supports the Qualcomm Quick Charge standard. Quick Charge 2.0 and 3.0 technologies are products of Qualcomm Technologies, Inc., a subsidiary of Qualcomm, Inc. Faster charging is becoming increasingly important as more powerful devices are released to the market. To support this, Qualcomm Technologies' Power Management ICs (PMICs) have optimized charging architectures within mobile devices by taking advantage of the Quick Charge technologies. Lattice delivers ICs for power adapters to ensure proper communication with the PMIC used in mobile devices. The LIF-UC device family offers flexible programming to enable customers to differentiate and future proof their designs. By updating firmware for Lattice solutions, engineers can quickly move from different generations of charging specifications, including Quick Charge, Battery Charging and Power Delivery, over standards such as USB Type-C. "As a result of our relationship with Qualcomm Technologies, we can bring customers a complete, endto-end solution that leads to a quicker time to market," said C.H. Chee, senior director of consumer marketing at Lattice Semiconductor. "This joint solution is optimized for flexibility in supporting multiple charging profiles, so that one charger can power today and tomorrow's mobile devices." Lattice's programmable charging controller is fully compliant with the USB Power Delivery v2.0 specification and when combined with Qualcomm Technologies' Quick Charge technology, it provides a flexible solution that reduces the time required to recharge batteries in mobile devices. Today there are Quick Charge 2.0 enabled smartphones, tablets, and wall adapters available from different manufacturers around the world. Quick Charge 3.0 is designed to charge devices up to four times faster than conventional technologies. www.BatteryPowerOnline.com Spring 2016 * Battery Power 33 http://www.BatteryPowerOnline.com
