1. Typical specifications are based on an ambient operating temperature of 25 °C and VIN = +50 V unless otherwise
2. Absolute classification current limits are configurable. See “5.2. Classification” and "5.3. Power-Up" on page 13.
3. Typical ICUT values are adjusted according to the input voltage to provide power limiting with approximately 5% margin
4. Overload current is within limits, typically in less than 1 ms.

specified.
against the 802.3 requirements. The maximum ICUT values are consistent with the IEEE requirement that Icut
maximum is less than 400 mA at the minimum allowed Vout of 44 V or 684 mA for PoE+ mode at the minimum allowed
Vout of 50 V.
