摘　　要：基于霍尔效应原理制成的霍尔电流传感器具有线性好,精准度高,不损耗被测电路能量,频带宽,可以测量直流交流脉冲电流等一系列优点,被广泛运用,并成为目前最主要最普遍的电流检测器件。文章设计了以型号为TBC25DS的霍尔传感器为核心的电流检测电路,测试结果表明该方法设计合理,成本低,响应快,误差小,并在精准度上达到了设计要求。Hall current sensor is based on the principle of Hall effect with many advantages, such as good linearity, high accuracy,no energy loss, wide frequency band, which can be employed to measure DC, AC and pulse current series of advantages. Thus it became one of the most popular current detection device. This paper designed the current detection circuit based on Hall sensor TBC25 DS, the measured results show the designed current monitor has some particular properties, such as low cost, fast response, small error, and high precision.
