ispPAC Power Management

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 ORing, sequencing, voltage monitoring, reset generation, trimming, margining, and more. The resulting solution meets the needs of a wide variety of circuit boards as opposed to using many types of single function ICs. Lattice programmability also enables power management designs to meet changing requirements without major circuit redesign or a board re-spin.
