具有電流調(diào)節(jié)功能的 18V、2A、H 橋電機驅(qū)動器

DRV8848 提供適用于家用電器和其他機電一體化應(yīng)用的雙 H 橋 電機驅(qū)動器。該器件可用于驅(qū)動一個或兩個直流電機、一個雙極性步進電機或其它負載。利用一個簡單的 PWM 接口便可輕松連接到控制器電路。\n\n每個 H 橋驅(qū)動器的輸出塊都包含配置為全 H 橋的 N 通道和 P 通道功率 MOSFET，用于驅(qū)動電機繞組。每個 H 橋都含有一個調(diào)節(jié)電路，可通過固定關(guān)斷時間斬波方案調(diào)節(jié)繞組電流。DRV8848 能夠從每個輸出驅(qū)動高達 2A 電流，在并聯(lián)模式下驅(qū)動高達 4A 電流（正常散熱，12V 且 TA = 25°C 時）。 \n\n低功耗睡眠模式可將部分內(nèi)部電路關(guān)斷，從而實現(xiàn)極低的靜態(tài)電流和功耗。 ? 雙路 H 橋電機驅(qū)動器 \n? 步進\n? 脈寬調(diào)制 (PWM) 控制接口\n? 每個 H 橋均提供高輸出電流 \n? 并聯(lián)模式下最大驅(qū)動器電流為 4A（12V 且TA = 25°C 時）\n? 工作電源電壓范圍為 4V 至 18V \n? 散熱增強型表面貼裝封裝 \n?
