<p><span>意法半导体推出了三款高精度高压双向电流检测放大器，这些放大器增加了便利的关断引脚，以最大程度地节省电能。</span></p>
<p><a href="https://www.st.com/en/amplifiers-and-comparators/tsc2010.html?icmp=tt20…;、</span><a href="https://www.st.com/en/amplifiers-and-comparators/tsc2011.html?icmp=tt20…;和</span><a href="https://www.st.com/en/amplifiers-and-comparators/tsc2012.html?icmp=tt20…;放大器的精密性让设计人员可以选择更小的敏感电阻值，将功耗降至最低水平。在</span><span>25°C</span><span>时，失调电压在</span><span>±200µV</span><span>范围内，温漂移低于</span><span>5µV /°C</span><span>，增益精度在</span><span>0.3</span><span>％以内，使器件能够满量程检测最低</span><span>10mV</span><span>的压降，提供一致且可信的测量值。</span></p>
<p><span>TSC2010</span><span>的增益变化为</span><span>20V/V</span><span>，</span><span>TSC2011</span><span>为</span><span>60V/V</span><span>，</span><span>TSC2012</span><span>为</span><span>100V/V</span><span>，能够为工业和汽车系统灵活地构建精确的电流测量、过流保护、电流监测和电流反馈电路。目标应用包括数据采集、电机控制、电磁阀控制、仪器仪表、测试测量以及过程控制。</span></p>
<p><span>这三款新放大器的双向检测功能允许用一个电流检测电路测量正反电流，有助于设计人员缩减物料清单成本。新产品还适用于高低边两种连接配置，允许高低边共用相同型号的器件，从而简化库存管理工作。</span></p>
<p><span>三款新产品的电源电压均在</span><span>2.7V</span><span>-</span><span>5.5V</span><span>范围内，进一步提高了应用灵活性。宽输入电压容差允许新产品在任何电源电压下检测从</span><span>-20V</span><span>至</span><span>70V</span><span>的共模电压电流。新产品具有高增益带宽乘积和快速压摆率(</span><span>TSC2010</span><span>的两项参数分别为</span><span>820kHz</span><span>和</span><span>7.5V/µs</span><span>)，确保测量精度高，响应速度快。</span></p>
<p><span>三款新产品内部集成</span><span>EMI</span><span>滤波器和</span><span>2kV HBM</span><span>(人体模型)的</span><span>ESD</span><span>防护功能，确保器件抗扰能力强，可在</span><span>-40°C</span><span>至</span><span>125°C</span><span>的工业温度范围内工作。</span></p>
<p><span>这三款新产品还有配套的</span><a href="https://www.st.com/en/evaluation-tools/steval-aetkt1v2.html?icmp=tt2002…;评估板，帮助设计人员快速启动使用任何一款器件的开发项目，加快产品上市时间。</span></p>
