说明

TMCS1100-Q1 是一款电隔离霍尔效应电流传感器,能够测量直流或交流电流,并具有高精度、出色的线性度和温度稳定性。低漂移、温度补偿信号链可以在器件的温度范围内实现 < 1% 的满量程误差。

输入电流流经内部 1.8mΩ 导体时,此导体产生的磁场可由集成式霍尔效应传感器进行测量。这种结构省去了外部集中器并简化了设计。低导体电阻可更大限度减少功率损耗和热耗散。固有的电镀绝缘在电流路径与电路之间提供了 600V 使用寿命内工作电压和 3kVRMS 基本型隔离。集成式电气屏蔽可提供出色的共模抑制和瞬态抗扰度。

输出电压与输入电流成正比,并具有四个灵敏度选项。固定的灵敏度允许 TMCS1100-Q1 使用单个 3V 至 5.5V 的电源运行,因此消除了比例式误差并提高了电源噪声抑制能力。当电流流入到正输入引脚时,电流极性被视为正极。VREF 输入引脚提供了一个可变零电流输出电压,允许进行双向或单向电流检测。

TMCS1100-Q1 消耗的最大电源电流为 6mA,所有灵敏度选项的额定工作温度范围均为 -40°C 至 +125°C。
