Microchip MCP6C02零飘移高边电流检测放大器解决方案

Microchip公司的MCP6C02是零飘移高边电流检测放大器,具有增益20, 50和100 V/V.共模输入范围(VIP)是+3V到+65V,差分模式输入范围(VDM = VIP – VIM)支持单向和双向应用.器件的电源在2.0V和5.5V间.SOT-23封装的器件工作温度-40C到 +125C (E-温度),而3×3 VDFN封装的器件工作温度-40C到 +150C (H温度).零飘移架构支持非常低的输入误差,允许设计采用并联电阻的值较低,从而更低的功耗.器件具有高DC精度:VOS为±1.65 μV, CMRR为154 dB, PSRR为138 dB,增益为±0.1%.主要用在满足AEC-Q100 Grade 0和Grade 1规范的汽车电子,马达控制,模拟电平转移,工业计算和电池监视器/测试器.本文介绍了MCP6C02主要特性,功能框图和框图,以及MCP6C02评估板主要特性,应用电路和评估板电路图,材料清单和PCB设计图.

The Microchip Technology Inc. MCP6C02 high-sidecurrent sense amplifier is offered with preset gains of20, 50 and 100 V/V. The Common-mode input range(VIP) is +3V to +65V. The Differential-mode input range(VDM = VIP – VIM) supports unidirectional andbidirectional applications.

The power supply can be set between 2.0V and 5.5V.Parts in the SOT-23 package are specified over -40Cto +125C (E-Temp), while parts in the 3×3 VDFNpackage are specified over -40C to +150C (H-Temp).

The Zero-Drift architecture supports very low inputerrors, which allow a design to use shunt resistors oflower value (and lower power dissipation).
