BQ51013AYFPR is a low-power, single-channel wireless power receiving solution that supports the Qi V1.2.4, PMA 1.2, and HyperAir (C1, C2) standards.
The BQ51013AYFPR is developed by Texas Instruments and built into a Multi-Chip Package (MCP) consisting of a low-voltage IC (BQ21004 KLB) and a wireless power receiver IC (BQ50402 KLA). It enables 7.5 W wireless charging, providing more charging power for fast charges for flagships and tablets.

Application Field

The BQ51013AYFPR is designed for Wireless and Extended Range Wireless Charging®, as well as radio-frequency (RF) sensing and processing applications. Specifically, it is suitable for side mounting in mobile electronics, such as mobile phones, tablets, and auxiliary device chargers. This solution helps reduce printed circuit board size, simplify power supply design, and conserve board real estate. Furthermore, it reduces system complexity and provides greater flexibility when developing complex applications.

Work Principle

The BQ51013AYFPR is capable of transferring up to 7.5 W of power in a reliable, flexible, and efficient manner. The system consists of a primary device (Transmitter) that provides a wireless power signal, and a secondary device (Receiver) that wirelessly extracts the power signal and converts it into an available power supply. The BQ51013AYFPR features an ultra-low-power sensitive mode of operation that allows for operation over extended ranges. This ‘extended range mode’ only requires a power input from the source, and will not cause any load on the host. This allows for the receive coil to be driven from the source at the same time as the transmit coil, providing a power transfer over greater distances than in typical setups.

The BQ51013AYFPR features an integrated sensorless Foreign Object Detection (sFOD) algorithm that constantly monitors the correct position of the receiver coil to ensure optimum efficiency. Additionally, the receiver is able to detect when the wireless power signal is no longer present, and will shut down to save power.

The integrated power management IC (PMIC) is able to regulate the output voltage, ensuring the optimal level is provided at all times. This keeps the power transfer efficient and reliable, and allows products using the BQ51013AYFPR to remain powered for extended periods of time. Furthermore, the PMIC provides protection against over-current and over-voltage conditions, keeping the device safe from component damage.

The BQ51013AYFPR is an easy-to-use and reliable solution for wireless charging applications that enables greater design flexibility and faster time-to-market. Its extensive range of features and its ability to detect Foreign Objects make it an ideal choice for many applications.
