具有電流調(diào)節(jié)和獨立半橋控制的 18V、2A 雙路 H 橋電機驅(qū)動器

DRV8847 器件是一款適用于工業(yè) 應(yīng)用、家用電器、ePOS 打印機以及其他機電產(chǎn)品 的雙 H 橋電機驅(qū)動器。本器件可用于驅(qū)動兩個直流電機、一個雙極步進電機或繼電器等其他負(fù)載。借助簡單的 PWM 接口，可與控制器輕松連接。DRV8847 器件由單一電源供電，支持 2.7V 至 18V 的寬輸入電源范圍。\n\n驅(qū)動器的輸出級由配置為兩個全 H 橋的 N 溝道功率 MOSFET 構(gòu)成，用于驅(qū)動電機繞組或四個獨立半橋（位于獨立橋接式接口）。固定關(guān)斷時間控制電橋中的峰值電流，該電流能夠驅(qū)動一個 1A 的負(fù)載（并行模式下 25°C TA 時，在散熱適當(dāng)?shù)臈l件下，可驅(qū)動 2A 的負(fù)載）。\n\n提供了 ? 雙路 H 橋電機驅(qū)動器 \n? 一個雙極步進電機\n? 2.7V 至 18V 工作電壓范圍\n?
