The ADM1069 is a Super Sequencer™ with Margining Control. It provides complete supervisory and sequencing solution for up to 8 supplies. It has a variety of features that make it very useful in power monitoring and regulation applications.
The ADM1069 is a single-chip solution designed for supply monitoring and sequencing in multiple supply systems. It integrates eight supply fault detectors capable of supervision to better than 1% accuracy and four selectable input attenuators allowing the monitoring of supplies up to 14.4 V on VH or 6 V on VP1-3.
The device features a logical core consisting of a state-machine-based sequencing engine that provides up to 63 different states for flexible control of outputs based on input conditions. It includes eight programmable output drivers (PDOs) capable of driving N-channel FET gates and four 8-bit voltage output DACs for closed-loop margining systems.
