The ispPAC-POWR1208 is a single-chip, fully integrated solution to supervisory and control problems encountered when implementing on-board power conversion and distribution systems. The ispPAC-POWR1208 provides several types of on-chip resources, which can be used to meet the requirements of these applications. Twelve analog comparators, each with independently adjustable references, provide the ability to detect when a voltage is greater than or less than a given threshold. Four timers make it straightforward to implement programmable delays. An embedded PLD supports the implementation of state machines and sequencers, providing embeddable intelligence in a power supply design.

This application note describes PAC-Designer's LogiBuilder system and shows how it can be used to develop power-supply control logic to be implemented in Lattice Semiconductor's ispPAC-POWR1208 power-supply sequencer IC.
