电源监控IC

ADI公司的电源监控IC 可针对数字电流和电压测量提供一种集成式解决方案,采用片内12位模数转换器(ADC)执行测量,并通过I2C接口通信。借助ADI公司的精密模拟设计技术,ADI产品比竞争器件的精度高两倍,可提供同类最佳精度(<±0.8%)。电源监控器使让业界唯一的监控器和时序控制器系列可在2至12个电源上实现<±1%的精度。

该器件设计用于当前先进的数据和电信基础设施,此类设备通常由极强大的处理器以前所未有的低内核电压驱动。凭借其史无前例的精度,电源监控IC能够精确监控处理器内核,以确保其在电压容限规格内工作,让电源和系统工程师能够将系统的正常工作时间最大化并优化系统的性能。
