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 “7.2. Classification” and "7.3. Power-Up" on page 14.
3. Typical ICUT values are adjusted according to the input voltage to provide power limiting with approximately 7% margin
4. Overload current is within limits, typically in less than 1 ms.
Description
