Overview

Description

The IDT P9030 is a highly-integrated single-chip Qi standard-compliant wireless power transmitter IC for power transmitter design A1. The device operates with a 19V adapter, and supplies an integrated half-bridge inverter for DC/AC conversion. It controls the transferred power by modulating the switching frequency of the half-bridge inverter from 110kHz to 205kHz at a fixed 50% duty cycle as specified by the Qi standard for an “A1” transmitter. The transmitter contains logic circuits required to demodulate and decode Qi-compliant message packets sent by the mobile device to adjust the transferred power.

The P9030 also features multi-mode operation, supporting both the Qi wireless power standard as well as customer proprietary protocols with dynamic detection and switching between protocols for maximum flexibility in wireless power transmission. Value-added proprietary features include advanced multi-layered Foreign Object Detection (FOD) for safety, 2-way secure authentication between base and mobile, and power delivery up to 7.5W for faster charging times. IDT’s wireless power transmission solution is complemented by its rich portfolio of wireless power receiver ICs; offering customers additional features for next-generation devices equipped with wireless power transfer capabilities.

Hello, I'm Jack Deans, Field Applications Manager with Integrated Device Technology. This tech video covers IDT's current lineup of magnetic inductive style wireless power transmitters as of July 2013. IDT designs and builds the central power controller IC. We also design and build reference boards and evaluation kits that are certified to the current QI specification. Now, a wireless power transmitter generates an oscillating magnetic field. A wireless power receiver recovers this energy and creates a low voltage DC current for the desired load. In this video, we are only covering magnetic induction style wireless power transmit solutions. 
 
This three coil design is our most popular design. It provides the receiver a physically larger charging area. The 9036-A is fully WPC version 1.1 compliant, which means it satisfies the new foreign object detection demands called out in that specification. The P9036 is version 1.1 compliant, but is an ideal choice for proprietary type designs that are looking for a reduced bill of materials. The WPC specification calls out a five watt solution. If IDT's wireless power transmitter and receiver are used together, we can transmit power up to 7.5 watts, which is above and beyond the WPC specification. Also, WPC A6 design is intended for 12-volt input voltage operation. Our solution can accept a wider input voltage range of between nine volts and 16 volts. The P9036 and P9036-A are fully WPC FOD compliant, which require a receiver to be used on the transmit pad to communicate power received information back to the transmitter. On top of that, IDT's devices have an advanced foreign object detection mode, a proprietary algorithm that senses whether or not a metallic foreign object is placed on the charger, with or without a receiver being on the transmitter. Normal wireless power communication requires a data path between the receiver to the transmitter. This data path provides real time, load current information, as well as other command and control packets. When the IDT transmitter is paired with the IDT receiver, our solution can provide a data path between the transmitter and the receiver in the opposite direction as well as secure authentication. 
 
The P9035 design is intended for five-volt input type applications. We offer the P9035 in an A and non-A version similar to the P9036, where the P9035-A is fully WPC version 1.1 compliant, and the non-A version is ideal for reduced bill of materials type applications. We support the A5 A11 coils. These designs also will work up to 7.5 watts when used with an IDT receiver. The input voltage range is not as wide as the 9036, but it does offer the advanced foreign object detection proprietary mode and the advanced two-way communication and secure authentication features. 
 
Now the 9030 is an ultra-low bill of materials solution. It can also deliver seven and a half watts of power transfer and accept a wide input operating voltage range as well. 
 
On this slide, we show three of the available transmitter evaluation kits we have. The board on the right is the A6 design and in the center of the circuitry is the IDT wireless power transmitter, controller IC. Closer to the coils are the pushing FETs and our controller will control these FETs and select which coil will provide the maximum amount of efficiency and power coupling to the receiver. On the left are two other eval kits. The top one is our A5 design. You'll notice the coil can be removed and other suppliers' coils bolted on. And below that is the P9030 design.  The components within that white silk screen outline are the only components needed to implement a wireless power solution. This is a very low bill of materials wireless power transmit solution. 
 
Here's a table listing the transmit ports we've been discussing today. They're all available now. Our roadmap includes products that have higher integration, higher power transfer, and more safety and reliability features. 
 
IDT offers comprehensive design support. We have complete reference design, application notes, as well as services such as design reviews, Qi pre-certification testing, and even complete solution development.
