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

集成电流检测和128微步分度器的36V、3.8A步进电机驱动器

MAX22210是一款2相步进电机驱动器。它集成了两个36V、3.8AMAX H桥。\n\n H桥FET的阻抗非常低，因此驱动效率较高且发热很少。总RON（高侧 + 低侧）的典型值为0.25Ω。\n\n MAX22210集成了一个精密的电流驱动调节电路和一个由STEP/DIR接口控制的128微步内置分度器。高微步分辨率和先进的控制技术可确保工作时保持平稳和安静。\n\n 流入两个低侧FET的电流由无损耗式集成电流检测(ICS)器件进行检测，然后会与所需的步进阈值电流进行比较。一旦电桥电流超过设定值(ITRIP)，器件就会强制衰减，并保持一段固定的关断时间(TOFF • 两个H桥的额定值为36V\n• 总RDS(ON) (HS + LS)：TA = +25°C时为250mΩ（典型值）\n• 每个H桥的电流额定值（TA = +25°C，典型值）\n•IFS = 3AMAX（内部电流驱动调节的满量程电流设置）\n• 集成电流控制\n• 可使用外部电阻配置满量程电流\n• 通过一路逻辑输入(HFS)提高低电流值的电流控制精度\n• 提供内部电流检测(ICS)功能，无需使用体积较大外部电阻器，提高了效率;
