ADA4523-1

• ADA4523-1用の全機能内蔵型評価用ボード
• 効率的な試作が可能
• ユーザ定義の回路構成
• エッジ・マウントSMAコネクタを装備
• 低消費電力アプリケーション向けのシャットダウン機能

EVAL-ADA4523-1ARMZを使用して、8ピン・マイクロ・スモール・アウトライン・パッケージ（MSOP）のシングル・チャンネル・オペアンプADA4523-1の評価を行うことができます。この評価用ボードのADA4523-1は、ゲインが101の非反転アンプとして設定されています。ADA4523-1のゲイン帯域幅積（GB積）の代表値は4MHzです。101のゲインを使用する場合、ADA4523-1の使用可能な帯域幅はおよそ39.6kHzに制限されます。この帯域幅制限は、ADA4523-1の330kHzの内部チョッピング周波数によって生成されるアーティファクトを緩和する、ローパス・フィルタとして作用します。

EVAL-ADA4523-1のレイアウトは反転入力と非反転入力に接続されるノードの構築に注意が払われているため、ADA4523-1の最大オフセット電圧より大きなオフセット電圧を引き起こす、パターンと部品の熱電対効果が軽減されています。ADA4523-1には、低消費電力アプリケーション向けにシャットダウン・モードも備わっています。EVAL-ADA4523- 1ARMZには、SDピンおよびSD_COMピン用テスト・ポイントが装備されており、シャットダウン機能を容易に使用できます。

EVAL-ADA4523-1ARMZは、バイパス・コンデンサを除き単純な取り付けが可能となるよう、主として0805サイズの抵抗とコンデンサで構成されています。ADA4523-1の最大電源電圧が55Vであるため、10µFのバイパス・コンデンサ（C1とC4）は高電圧定格に対応できるよう、2220のパッケージ・サイズとなっています。ADA4523-1の詳細については、ADA4523-1のデータシートを参照してください。このデータシートは、EVAL-ADA4523-1ARMZの使用時に、本ユーザ・ガイドと併せて参照する必要があります。

The AD-ACEVSECRDSET-SL is a complete Type 2 EVSE 3.6 kW charging cable solution, providing a reference design intended for evaluation and prototyping of electric vehicle (EV) charging systems.

The system includes a 3-channel isolated sigma-delta (Σ-Δ) ADC for voltage and current measurement on the single-phase power input and measurement of the relay voltage for solder contacts detection and relay state of health. Safe operation is enabled by the inclusion of a 6 mA DC / 30 mA rms RCD. Detection of overvoltage, undervoltage, overcurrent, overtemperature and EV diode presence is also available.

A MAX32655 low-power, ARM^® Cortex^®-M4 Microcontroller implements the logic for system control and communication with the EV over the control pilot interface. A programming and debugging interface are included. The MAX32655 Bluetooth 5.2 interface enables connectivity to external devices.

The design is accompanied by an open-source software stack and reference applications, enabling custom software development to start from a proven implementation validated to meet the applicable standards. An external programmer such as the MAX32625PICO MAXDAP Programming Adapter, or any other similar programmer supporting the SWD interface, is required to enable firmware programming and debug.

The system is designed to comply with the IEC61851 and IEC62752 standards.

The AD-ACEVSE22KWZ-KIT is a reference design for the metrology subsystem plus selected other features of a level 2, 7 kW to 22 kW AC electric vehicle supply equipment (EVSE). It includes the ADE9113 isolated Σ-Δ analog-to-digital converter (ADC) coupled with the ADE9178 metrology DSP to accurately measure energy delivered to an electric vehicle (EV). It includes the MAX32672 ultralow- power ARM^® Cortex^®-M4 processor, a cost-effective, highly integrated, and highly reliable 32-bit microcontroller to accumulate energy measurements and securely send it to a host for display. A charge control state machine is run on the microcontroller to transition through different charge states when a charging plug is inserted into an electric vehicle. The kit includes a flexible printed circuit (FPC) connector and LCD to read the energy measurements and state transitions during a charging cycle. The power input/output, control pilot (CP), and proximity pilot (PP) signals are exposed on connectors at the edge of the board. The energy delivered to the EV is measured as a voltage drop across shunts and a resistor ladder network, which makes it easy to set up the boards in the field.
