Working Principles

The ADM1065ACPZ is designed to provide precise control and monitoring of power supply sequencing in complex systems. It utilizes an internal state machine that allows for flexible power-up and power-down sequencing. The I2C interface enables easy configuration of output voltage levels and sequencing parameters.

The device continuously monitors the input and output voltages, as well as the current levels, to detect any faults such as overvoltage, undervoltage, or overcurrent conditions. In case of a fault, the ADM1065ACPZ can take appropriate actions, such as shutting down the affected channel or generating an alert signal.
