CXEP2324隔离传感器IC使第四代CXEP2335x芯片系统(SOC)能够使用非隔离传感器,如电阻分路,而无需昂贵的非线性隔离变压器或CT。隔离由在CXEP2335x和隔离传感器IC之间形成双向数字通信链路的低成本脉冲变压器提供。CXEP2324隔离传感器IC包含一个22位增量西格玛ADC、一个带差分输入的放大器、一个精确的电压基准、一个温度传感器,以及由CXEP2335x提供的电源脉冲供电的电源电压发生器。与CXEP2335x计量SOC一起,隔离传感器IC提供了前所未有的物料清单成本降低、抗磁干扰能力,提高了单相和多相应用的可靠性。这些计量SOC在工业温度范围内运行,并可在8针引线(Pb)自由SO封装中使用。

产品概述 返回TOP
The CXEP2324 isolated sensor ICs enable 4th-generation CXEP2335x systems-on-chips (SoCs) to use nonisolating sensors such as resistive shunts without the need for costly and nonlinear isolation transformers or CTs. Isolation is provided by low-cost pulse transformers that form a bidirectional digital communication link between the CXEP2335x and the isolated sensor ICs.The CXEP2324 isolated sensor ICs contain a 22-bit delta-sigma ADC, an amplifier with differential inputs, a precision voltage reference, a temperature sensor, and a supply voltage generator that is energized by power pulses provided by the CXEP2335x. In conjunction with the CXEP2335x metering SoCs, the isolated sensor ICs offer unprecedented BOM cost reduction, immunity to magnetic tampering, and enhanced reliability for single-phase and polyphase applications.These metering SoCs operate over the industrial temperature range and are available in an 8-pin lead(Pb)-free SO package.
