Cota Chipset Provides Wireless Power at a Distance Without the Need for a Charging Pad

Ossia, the innovative company making Real Wireless Power a reality, has unveiled the next generation reference design kit for Cota Chipset, the first commercially available chipset for real wireless power at a distance. Manufacturers can purchase the new reference design kits immediately. Ossia made the announcement at CEATEC JAPAN 2017.

Cota delivers wireless power without plugs, wires, or charging pads. Cota is inherently safe and can power multiple devices in motion even without line of sight across several meters. All Cota-enabled devices can be activated, managed, and monitored via the Cota Cloud platform.

The reference design kit includes two new components: Cota Wireless Power Receiver Chip and Cota Wireless Power Transmitter Chip. Reference design kits for both chipsets are commercially available for original equipment manufacturers (OEMs) to customize and install in their products. Si-Ware Systems, one of the valued partners in the Ossia ecosystem, provides both Cota chips as application-specific integrated circuits (ASICs) on one of the world's mainstream process nodes for scalability and value. OEMs may license receiver and transmitter reference designs from Ossia together or separately.

The Cota Wireless Power Receiver Chip enables devices to receive wireless power. With a chip size of 5mm x 5mm, the chip easily fits in smartphones, wearables, sensors, and other Internet of Things (IoT) devices. It can receive up to 4 watts of incoming radio frequency (RF) power from as many as four antennas simultaneously. Compared to earlier designs, the new receiver charges faster, stays cooler, and features ultra-low power sleep mode, which ensures the chip is only activated in range of a transmitter.  

The Cota Wireless Power Transmitter Chip delivers wireless power to devices that contain the Cota Wireless Power Receiver Chip. With a monolithic multiple antenna management chip in the size of 4mm x 4mm, the transmitter can be built into many form factors such as ceiling tiles, tables, desks, glass, televisions, and automobile dashboards. Compared to prior generations, the new transmitter chip charges devices faster, delivering roughly twice as much power safely. The transmitter automatically detects Cota-enabled devices and includes a temperature-sensing unit to prevent overheating. Click here for more information.
