Wireless Power Transfer Function
Qi – Compliant Wireless Charging: The BQ51013BRHLR is designed to support Qi – compliant wireless power transfer. This allows it to work with a wide range of Qi – enabled devices such as smartphones, smartwatches, and other portable electronics. It provides a convenient way to charge these devices without the need for a physical charging cable.
Efficient Power Transfer: It is engineered to achieve efficient energy transfer from the wireless power transmitter to the receiver – equipped device. The power transfer efficiency is optimized to minimize energy loss during the charging process, ensuring that a significant portion of the power supplied to the transmitter is effectively delivered to the device being charged.
Power Receiver Management
Input Power Conditioning: The device manages the input power received wirelessly. It conditions the received power, which may have fluctuations or interference, to a stable and suitable form for the internal charging circuitry of the connected device. This includes functions like voltage regulation and filtering to provide a clean power supply for battery charging.
Battery Charging Control: It oversees the charging of the device’s battery. It can implement different charging algorithms and modes depending on the battery type and requirements. For example, it can handle the charging process of lithium – ion batteries, including functions such as constant – current and constant – voltage charging stages to ensure the battery is charged safely and effectively.
Communication and Feedback Mechanisms
Communication with Transmitter: The BQ51013BRHLR has the ability to communicate with the wireless power transmitter. This two – way communication allows for the negotiation of power transfer parameters such as power level and frequency. It also enables the receiver to send feedback to the transmitter about the power requirements and the charging status of the device.
Status Reporting: It provides status information about the charging process. This can be used by the device’s host system to display charging – related information to the user, such as the charging progress, any errors or warnings during the charging process, and whether the device is properly aligned for optimal power transfer.
Protection and Safety Features
Overvoltage Protection: The product is equipped with overvoltage protection mechanisms. If the input voltage received during the wireless charging process exceeds a safe level, it will take measures to protect the device’s internal circuitry and the battery. This could involve reducing the power transfer or shutting down the charging process temporarily to prevent damage from overvoltage.
Overcurrent Protection: It also has overcurrent protection. In case of an abnormal increase in the charging current, which could be due to a short circuit or other faults, it will limit or cut off the current to safeguard the device and its components. Additionally, it may have thermal protection features to prevent overheating during the charging process.
System Compatibility and Integration
Wide Device Compatibility: Due to its Qi – compliance and standard communication protocols, it is highly compatible with a variety of wireless power transmitters and different types of mobile and portable devices. This makes it a versatile choice for integrating wireless charging capabilities into many consumer electronics products.
Compact and Easy Integration: The BQ51013BRHLR is designed to be compact, which facilitates its integration into space – constrained electronic devices. Its standard pin – out and well – defined interfaces make it relatively easy for designers to incorporate it into their product designs, enabling the addition of wireless charging functionality without significant redesign efforts.
