- Application NoteAI-generated Summary: 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.
- Application NoteAI-generated Summary: 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.
- Application NoteAI-generated Summary: 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.
- Application NoteAI-generated Summary: The document presents typical performance characteristics of various inductors used in DC-DC converters, focusing on ripple voltage versus output current at different system voltages. It compares multiple inductor models, showing their behavior under varying loads. Additionally, it provides Renesas Electronics website and contact information for further inquiries. The revision record notes the first edition release date as August 10, 2017.
- Application NoteAI-generated Summary: The document details the configuration and operation modes of a low power wireless charging system using TxIC and RxIC components. It explains various operation modes including Stand Alone, ATPC, MCU Control, and Wired Charging, describing how registers control power transmission and communication. Power transmission timing and error detection mechanisms are also covered, highlighting register settings and communication interfaces for system control.
- Application NotePDF 397 KB an1684 Jan 19, 2004AI-generated Summary: The document outlines important legal disclaimers and usage guidelines for semiconductor products. It emphasizes user responsibility for product design and safety, disclaims liability for damages, and clarifies no intellectual property licenses are granted. Products are categorized by quality grades with specific application recommendations. Users must comply with laws, avoid unauthorized modifications, and ensure safe use within specified conditions. Contact details for Renesas Electronics sales offices worldwide are provided.
- Application NotePDF 509 KB an1681 Jan 19, 2004AI-generated Summary: The document explains grounding techniques for PCB layouts using a dual op amp example on a single-layer copper board. It compares three grounding schemes: a center spine ground trace, an outer ground plane, and a split/star ground plane, highlighting the benefits of single-point grounding to minimize noise and antenna effects. It emphasizes following current paths, minimizing loop lengths, and ensuring close forward and return paths to reduce interference. The document also includes disclaimers on product use, quality grades, safety, and legal compliance.
