Temperature Monitoring and Fan Control with Platform Manager 2 Technical Note
■Platform Manager™ 2 devices are fast-reacting, programmable logic based hardware management controllers. Platform Manager 2 devices are an integrated solution combining analog sense and control elements with scalable programmable logic resources. This integrated approach allows Platform Manager 2 designs to address Power Management (Power Sequencing, Voltage Monitoring, Trimming and Margining), Thermal Management (Temperature Monitoring, Fan Control, Power Control), and Control Plane functions (System Configuration, I/O Expansion, and others). This technical note focuses on the Temperature Monitoring and Fan Control features, and the process for integrating these features into the overall hardware management control.
■The information in this technical note applies to all Platform Manager 2 designs. Platform Manager 2 designs can be built using several combinations of Lattice devices as listed in Table 1. Throughout the remainder of this document, the use of ASC refers to either the LPTM21L or the L-ASC10 hardware management expander.
