36V, 3.8A Stepper Motor Driver with Integrated Current Sense and 128 Microstep Indexer

General Description The MAX22210 is a 2-phase stepper motor driver. It integrates two 36V, 3.8AMAX H-bridges. The H-bridge FETs have very low impedance that result in high driving efficiency and minimal heat generated. The typical total RON (high side + low side) is 0.25Ω. The MAX22210 integ

集成電流檢測和128微步分度器的36V、3.8A步進電機驅(qū)動器

MAX22210是一款2相步進電機驅(qū)動器。它集成了兩個36V、3.8AMAX H橋。\n\n H橋FET的阻抗非常低，因此驅(qū)動效率較高且發(fā)熱很少?？俁ON（高側(cè) + 低側(cè)）的典型值為0.25Ω。\n\n MAX22210集成了一個精密的電流驅(qū)動調(diào)節(jié)電路和一個由STEP/DIR接口控制的128微步內(nèi)置分度器。高微步分辨率和先進的控制技術可確保工作時保持平穩(wěn)和安靜。\n\n 流入兩個低側(cè)FET的電流由無損耗式集成電流檢測(ICS)器件進行檢測，然后會與所需的步進閾值電流進行比較。一旦電橋電流超過設定值(ITRIP)，器件就會強制衰減，并保持一段固定的關斷時間(TOFF ? 兩個H橋的額定值為36V\n? 總RDS(ON) (HS + LS)：TA = +25°C時為250mΩ（典型值）\n? 每個H橋的電流額定值（TA = +25°C，典型值）\n?IFS = 3AMAX（內(nèi)部電流驅(qū)動調(diào)節(jié)的滿量程電流設置）\n? 集成電流控制\n? 可使用外部電阻配置滿量程電流\n? 通過一路邏輯輸入(HFS)提高低電流值的電流控制精度\n? 提供內(nèi)部電流檢測(ICS)功能，無需使用體積較大外部電阻器，提高了效率;
