Description
The MAX5969A/MAX5969B support a 2-event classification method as specified in the IEEE 802.3at standard and provide a signal to indicate when probed by Type 2 power-sourcing equipment (PSE). The devices detect the presence of a wall adapter power-source connection and allow a smooth switchover from the PoE power source to the wall power adapter.
The MAX5969A/MAX5969B also provide a power-good (PG) signal, two-step current limit and foldback, overtemperature protection, and di/dt limit.
The MAX5969A/MAX5969B are available in a space-saving, 10-pin, 3mm × 3mm, TDFN power package. These devices are rated over the -40°C to +85°C extended temperature range.
