Power Sequencing Reference Design Using Load Switches

1 января 2018

This reference design demonstrates various power sequencing configurations using load switches. By using integrated load switches, the timing of each voltage rail can be adjusted independently. Each voltage rail can be controlled without extensive processor intervention or external digital components. This design is useful in applications such as multi-function printers (MFPs) and set-top box (STB), where specific timing sequences are required to turn on various subsystems and processor rails.

Особенности

Three different Power Sequencing configurations: CT Configuration, QOD configuration, and independent GPIO configuration Adjustible timing thresholds using CT and QOD pins Pin-to-pin footprints allow for swapping between multiple load switches for different voltage, current, and Ron requirements Load switches offer smaller solution size and lower component count when compared to Discrete MOSFET solutions
