IDT has developed a single-chip wireless power transmitter accompanied by a high-output-power single-chip receiver solution.
The IDTP9030 and IDTP9020 comprise a wireless power transmitter and receiver solution designed to meet the Wireless Power Consortium (WPC) Qi standard, which ensures interoperability with any other device meeting the standard.
Both transmitter and receiver are capable of multi-mode operation, supporting both the Qi standard as well as proprietary formats for added features, improved safety and increased power output capability. Built-in protocol detection enables dynamic switching between Qi and proprietary modes, creating seamless transitions and a trouble-free user experience. These devices can be used in a myriad of mobile applications for convenient battery charging.
The IDTP9020 is a high-efficiency wireless power receiver delivering up to 5 W in Qi mode. When used with the IDTP9030 transmitter in a proprietary configuration, it can deliver up to 7,5 W. The devices also feature proprietary multi-layered foreign object detection (FOD), utilising sophisticated multi-parameter algorithms to assure a high level of safety while avoiding FOD false alarms.
The solution features over-temperature, over-voltage and over-current protection. In addition, the receiver includes support for charging the battery via USB cable when a wireless charging station is not available, eliminating the need for external USB adaptor switches in mobile devices.
