    芯片使用注意事項
    1、 以上推薦電路及參數(shù)僅適用于普通遙控車玩具,其他玩具及電機驅(qū)動在使用TC118時請根據(jù)實際情況來使用。
    2、 持續(xù)電流驅(qū)動能力受封裝形式、VDD、VCC、芯片差異及環(huán)境溫度、PCB材料及厚度等因素影響,規(guī)格書給出參數(shù)僅供參考。在實際使用中請根據(jù)產(chǎn)品考慮一定的余量。
    3、TC118S 采用MOS 工藝設(shè)計制造,對靜電敏感,要求在包裝、運輸、加工生產(chǎn)等全過程中需注意做好防靜電措施。
    4、馬達(dá)啟動瞬間的電流值建議不要超過2.5A。
