Working Principles

The MAX16129UAAGA+T operates by continuously monitoring the input voltages of the connected power supplies. It compares these voltages against programmable threshold levels to detect overvoltage and undervoltage conditions. The IC also monitors the power-fail condition by detecting a significant drop in the input voltage.

The sequencing time delay feature allows controlled power-up and power-down sequences by delaying the activation or deactivation of each channel. This ensures that the power supplies are turned on or off in a specific order, preventing potential issues such as voltage spikes or current surges.

In case of a fault condition, the MAX16129UAAGA+T provides independent fault outputs for each channel, allowing system-level fault indication. This enables quick identification and troubleshooting of any power-related issues.
