Lattice LPTM10-12107平台电源管理开发方案

Lattice 公司的平台电源管理器件包括连个器件: LPTM10-1247和LPTM10-12107,LPTM10-1247能监视12个电压源,支持47个数字输入和数字输出组合,而LPTM10-12107监视多达12个电压源,支持107个数字输入和数字输出组合.两个器件包括电源管理部分和数字板级电源管理部分.电源管理部分包括可编程阈值,精度0.7%的差分输入比较器,10位ADC和用来调整电源和富余量的可调整区块;数字板级电源管理部分由640-LUT FPGA和可编程逻辑接口I/O组成,典型应用包括无线基础设备,网络核心设备,服务器,数据存储和高端工业仪表等.本文介绍了LPTM10-12107主要特性,方框图,平台管理典型应用框图以及平台电源管理和数字功能方框图, 平台电源管理评估板电路图和材料清单(BOM).

The Platform Manager product family consists of two devices, the LPTM10-1247 and LPTM10-12107. The LPTM10-1247 device can monitor 12 voltage rails and supports 47 combined digital inputs and digital outputs, while the LPTM10-12107 monitors up to 12 voltage rails and supports 107 combined digital inputs and digital outputs. Functionally, these devices include both a power management section and a digital board management section. The power management section consists of a programmable threshold, precision differential input comparator block with an accuracy of 0.7%, a 48-macrocell CPLD, programmable hardware timers, a 10-bit analog to digital converter and a trim block for the trimming and margining of supplies. The digital board management section consists of a 640-LUT FPGA and programmable logic interface I/O.
