RAA457100GBM

AI 生成的摘要: The document details the connection and setup of the RAA458100GNP and RAA457100GBM wireless charging evaluation kits, including TX and RX board pin configurations for ATPC Mode (AT4). It explains power supply connections, emphasizing not to connect mobile batteries and DC power simultaneously. The host adaptor RTKOEF0029Z00001BJ enables PC control via USB and 2-wire serial communication, with driver installation required only for Windows 7. The wireless charging control tool runs on Windows 7 and 10 without installation, preserving user settings between sessions.

AI 生成的摘要: The document details the register access methods between the transmitter system and the MCU of the receiver system during AT3 operation mode. It explains the wireless charging system configuration and outlines the procedures for writing and reading RxMCU registers via Tx2Rx WPT communication. The procedures emphasize confirming the normal operation of the RxIC's DCDC converter before accessing registers to ensure reliable communication. The document includes step-by-step sequences for setting slave addresses, triggering communication, confirming write/read completions, and handling abnormal converter conditions.

AI 生成的摘要: The document explains methods to read the average input current of a bridge circuit in wireless charging transmitters. It details two modes: ATPC Mode and MCU Control Mode. In ATPC Mode, the TxMCU must confirm the bridge driver circuit is active before reading registers to maintain A/D conversion accuracy. In MCU Control Mode, offset calibration is recommended by reading and subtracting the offset current from the measured current. The document includes transmitter configurations and step-by-step register reading procedures for both modes.
