東芝推出高解析度微步進馬達驅動IC

February 6, 2020

Toshiba Electronic Devices & Storage Corporation

TC78H670FTG

東芝電子元件及儲存裝置株式會社(東芝)推出最新微步進馬達驅動IC產品TC78H670FTG。這款IC最大額定值為18V/2.0A[1],可驅動各種工作電壓的馬達。已量產啟動。

新款IC可透過2.5V至16V供電電源驅動128微步進馬達。其電源來源可由USB供電、電池供電和標準9-12V系統元件,它還能與1.8V介面配合使用,從而連接各種主機和微控制器。

東芝最新的[2] DMOS製程確保TC78H670FTG具有卓越的品質與低導通電阻。該製程還有助於這款IC實現超低待機電流。此IC採用QFN16超小封裝,並透過整合電流檢測電阻來減少外部零件的使用,從而降低成本,精簡電路,節省PCB板佈線空間。

產品特點

  • 緊湊封裝(QFN16 3.0mm×3.0mm)
  • 低導通電阻(VM = 12V時Ron =0.48Ω)
  • 中低電壓範圍為2.5V至16V,介面電壓範圍為1.8V至5.0V
  • 0.1μA的超低待機電流
  • 平穩、無噪音運作馬達並減少振動;透過微步控制提高旋轉角度精度[3]

應用

相機、監控攝影機、可攜式印表機、掌上型掃描器、微型投影機和智慧手機
