Multi-Standard Adaptive Coupling Receivers

WiPQTUS delivers industry’s broadest portfolio of low-cost, ultra efficient, multi-standard adaptive coupling wireless power receivers ranging from 2W to 50W addressing the needs of consumer and industrial portables. WiPQTUS Multi-Standard Adaptive Coupling wireless power Receivers are of small size and low height and can be easily integrated into wearables, smartphones, tablets, notebooks, power tools, mobile POS, etc. By virtue of their adaptive coupling, WiPQTUS receivers have outstanding thermal performance. In combination with WiPQTUS Adaptive Coupling Transmitters, WiPQTUS receivers deliver large X-Y charging area, Z-height, orthogonal charging, multi-device charging and safety features.

50W/30W/15W/10W/2W Adaptive Coupling Wireless Power Receivers for Notebooks, 2-in-1s, Tablets, Phablets, Smartphone, Wearables, Power Tools and other Portables:

WiPQTUS Adaptive Coupling (AC) Receivers deliver industry leading thermal performance, transient response and offer industry’s broadest power range – from 2W per receiver to 50W per receiver.

WiPQTUS AC Receivers deliver their full rated power with low-height, low-cost, mass volume electromagnetic coil structures. Via patent-pending AC technology, the WiPQTUS Receiver is aware of the level of coupling with the transmitter. Based on the level of coupling and the amount of power drawn by the downstream load (battery charger, system, PMIC), the AC Receiver rapidly adjusts its operating point to deliver the required power with the best thermal performance. WiPQTUS Receiver’s good thermal performance helps keep the portable cool during charging even when drawing significant power.

WiPQTUS AC Receivers are multi-standard compatible. They include versatile sensing mechanism and algorithm to identify the protocol of the transmitter. When placed on Qi transmitters, the WiPQTUS AC Receiver detects and switches into Qi operating mode. They communicate with the transmitter in a Qi-way and smoothly deliver the received power from the transmitter to the downstream load. Similarly, when placed on PMA transmitters (such as those in Starbucks), the WiPQTUS AC Receiver detects and switches into PMA operating mode. They communicate with the transmitter in a PMA-way and smoothly deliver the received power from the transmitter to the downstream load.

WiPQTUS Receivers complement existing standards and deliver additional value such as better thermal performance to help promote the rapid adoption of wireless charging in portables.

Portables such as Wearable devices (MOTO-Watch), smartphones (Nokia-Lumia) and Tablets (Asus-Google Nexus7) when charged wirelessly are typically charged in Planar Charging mode. In planar charging, the transmitter and receiver are facing each other either head-on (tightly coupled) or offset (loosely coupled). Planar charging is ideal for portables that have a flat surface such as smartphones, tablets and notebooks. It enables wireless charging at high efficiency.

Planar charging is not ideal for portables which do not have any flat surface (circular bracelet style) or have a small amount of flat surface such as the many Wearable devices like Fitness Trackers (FitBit, Microsoft Band), Smart Watches (Samsung Galaxy Gear, Apple Watch), Smart glass (Google Glass), hearing aids and heart-rate monitors. For such Wearable devices, Orthogonal Charging is ideal. In Orthogonal charging, the transmitter and receiver may not be facing each other; they can be rotationally misaligned and in the worst case, could be fully perpendicular to each other.

WiPQTUS AC Receiver is the industry’s first orthogonal charging receiver that is based of simple, flat electromagnetic design. Via AC technology, the WiPQTUS Receiver senses the level of coupling and transforms its operation. In conjunction with the WiPQTUS AC Transmitter, the WiPQTUS Receiver delivers the requested power to the downstream load (battery charger, system, PMIC) even in orthogonal alignment. Wearable devices can hence be charged even when the receiver is fully perpendicular to the transmitter. Consumers enjoy incredible positional freedom and ease of use for charging their Wearables via such a capability.

WiPQTUS Receiver in conjunction with WiPQTUS transmitter delivers outstanding transient load response. After detecting and authenticating each other, the WiPQTUS Receiver and transmitter switch into a proprietary ultra-low-cost in-band communication mode. This communication mode is designed ground-up to enable rapid convergence of operating point to changes in the load and receiver position. As power levels are scaled up and as charging area is widened, fast, accurate and efficient power control is very critical to ensure safe and damage-free charging of the portables. WiPQTUS Receiver in conjunction with WiPQTUS transmitter delivers just that.

WiPQTUS Receiver includes support for simultaneous charging of upto 3 WiPQTUS receivers, upto 10W each. After detecting and authenticating each other, the WiPQTUS receiver and transmitter switch into a proprietary ultra-low-cost in-band communication mode. This communication mode is designed ground-up to enable the WiPQTUS transmitter to simultaneously listen to the needs of the multiple receivers. Like a good parent juggling with the needs of their children, the WiPQTUS AC Transmitter comes with many patent-pending algorithms and techniques to simultaneously satisfy the power needs of multiple receivers. WiPQTUS Transmitter is designed to manage the receiver’s requests even if they were dramatically different. For eg: one receiver wants zero power while the other wants 10W.

WiPQTUS Receivers include appropriate power consumption reporting for Qi-1.1 and WiPQTUS Transmitters. Power consumption reporting is implemented in planar and orthogonal charging modes and over the entire charging area. Via such information, Qi-1.1 and WiPQTUS Transmitter detect the presence of foreign metal objects on the charging surface and shutdown charging to avoid unintended heating and damage.

WiPQTUS Receivers include facilities to shutdown charging under several conditions. WiPQTUS Receivers include various techniques to protect the receiver from a power overload or a rogue transmitter.

WiPQTUS AC Receivers are very flexible and the entire operating behavior can be redefined by the OEM if needed. They have excellent provisions for transfer of OEM proprietary packets and for addition of visibility and controls to enable the OEM to deliver differentiated solutions.
