The advanced Microchip wireless receiver is compatible with Qi 1.2 base stations and is able to draw up to 15W of power that can be used to run portable devices or charge batteries. It allows users to quickly incorporate this receiver into their designs without dealing with the Qi protocol state machine and communication.

This implementation consists of a wireless receiver and a synchronous buck converter used to charge batteries. A low-cost, general purpose 8-bit microcontroller handles the Qi state machine, communication to and from the base station, the Li-Ion battery charging state machine, and regulates the buck converter output voltage and input current. The advanced Microchip Qi1.2 wireless receiver is backwards compatible with Qi1.1 5W base station and should be able to detect the base station capabilities.

Microchip has developed the Residential Solar Breaker Reference Design featuring the HV9901, as an example reference breaker solution for single phase residential solar installations. All the Reference Design components, including the HV9901, are rated to 125°C, a critical feature for these systems as they are required to operate in the high temperature environment of the solar panel. This higher rating helps to ensure long operating life of these systems in this harsh environment. The energy tracking is supported by MCP39F511A. Power monitoring in solar installations provides multiple benefits to the customer like fault monitoring to detect a faulty inverter or panel which could cause hazardous situations and alerts in case of drop in performance. Provision for additional safety and robustness comes from the ability to install the MCP9701, which can be used to adjust the performance due to over temperature conditions (like disconnecting the inverter from the load in case of excessive temperature.)
