目录产品概述 返回TOP The CXEP2339 isolated sensor ICs enable 4th-generation CXEP2339 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 CXEP2339 and the isolated sensor ICs.The CXEP2339 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 CXEP2339. In conjunction with the CXEP2339 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产品特点 返回TOP Reduce BOM by Replacing Expensive Current Transformers with Current Shunts Compatible with Shunt Resistors as Low as 50 Accurate Measurement 22-Bit ADC On-Chip Power Monitoring Exceeds IEC 62053/ANSI C12.20 Standards Galvanic Isolation Through Pulse Transformer Provides Power, Bidirectional Data, and Timing Reference 3.3mW Typical Consumption On-Chip Power Monitoring 应用范围 返回TOP Electricity Meters 技术规格书(产品PDF) 返回TOP 需要详细的PDF规格书请扫一扫微信联系我们,还可以获得免费样品以及技术支持!
