東芝與Mikroe合作推出馬達驅動IC開發評估板

作者 : Toshiba

使用由Mikroe提供的Click boards以及電路圖和樣本軟體,可以讓工程師輕鬆地對東芝馬達驅動IC進行評估。所有的Click boards評估板都能夠完全相容mikroBUS的開發套件。

東芝(Toshiba)宣佈與MikroElektronika (Mikroe)合作推出搭載東芝馬達驅動IC的Click boards開發評估板。Mikroe是一家設計和製造用於嵌入式系統開發的軟硬體工具的公司。客戶可透過由Mikroe在線上銷售的Click boards板直接訂購。

東芝擁有高度整合的馬達驅動IC開發歷史,而在業界廣受推崇。產品包含控制多種應用中的直流有刷馬達、直流無刷馬達和步進馬達,多樣性的馬達驅動IC產品線,適用於工業設備、家電和OA自動化設備。使用由Mikroe提供的Click boards以及電路圖和樣本軟體,可以讓工程師輕鬆地對東芝馬達驅動IC進行評估。所有的Click boards評估板都能夠完全相容mikroBUS的開發套件。

以下為五種搭載東芝馬達驅動IC新產品的Click boards,包含直流有刷馬達、直流無刷馬達和步進馬達:

  • 搭載東芝TB67H451FNG的直流有刷馬達驅動Click boards為先進的PWM斬波式集成直流馬達驅動器。TB67H451FNG採用東芝BiCD製程,可支援從4.5V至44V的供電電壓範圍。H-Brdige MOSFET的低導通電阻有助於提供較大電流並產生較低熱量。TB67H451FNG並具備正轉、反轉、剎車和停止這四種馬達工作模式。
  • 搭載東芝TB67H450FNG – PWM斬波式直流馬達驅動IC。可支援從4.5V至44V的供電電壓範圍,供電電流最高可達3.5A。TB67H450FNG的低導通電阻MOSFET有助於降低功耗,進而提高馬達工作效率。採用簡單的雙輸入控制,支援馬達以正轉、反轉、剎車和停止這四種模式工作。
  • 搭載東芝TC78B009FTG無需霍爾感測器即可驅動3相直流無刷馬達。其還內建閉迴路(Closed Loop)速度控制功能,能在電壓和負載發生動態波動的情況下調節和保持馬達轉速。內建非揮發性記憶體(NVM)允許設計者創建並保存速度配置。綜合這些特性,減少對外部速度控制器的需求。
  • 搭載東芝TB67S128FTG其為一款雙相雙極步進馬達驅動IC,絕對最大輸出為50V/5A。東芝的創新技術幫助MOSFET驅動實現了低功耗以及0.25Ω的低導通電阻。它透過步進控制輸入簡化控制。步進控制輸入可雙向驅動步進馬達,步長從全步到1/128步可調。此外,它也提供了先進的電流檢測系統、主動增益控制和多種錯誤檢測功能。
  • 搭載東芝TC78H670FTG為一款雙極步進馬達驅動IC,可支援全步到1/128步的步進範圍。1/128步這樣的較小步長有助於降低馬達產生的雜訊和振動,實現馬達平穩運行。該IC可支援2.5V至16V的電壓範圍,適用於USB或電池供電應用。
