IN-SYSTEM PROGRAMMABLE POWER SUPPLY MANAGEMENT CHIP TM Power Manager II Integrate Common Board Power Management Functions Lattice’s Power Manager II devices feature an innovative programmable core and precision analog sensors to reduce component count and increase reliability. Power Manager II devices significantly reduce cost by integrating power management board functions such as hot-swap controllers, power supply OR’ing, sequencing, voltage monitoring, reset generation, trimming, margining, and more. The resulting solution can be customized to meet the needs of a wide variety of circuit boards as opposed to using many types of single function ICs. And Lattice programmability enables power management designs to meet changing requirements without major circuit redesign or a board re-spin.
