Product Description

The MP8001/MP8001A are IEEE 802. 3 af POE compliant Powered Device (PD) controllers. they include detection and classification modes as well as a 100V output pass device having a temperature compensated current limit over the specified temperature range. Thermal protection is built in to accommodate both transient and/or overload conditions, shutting the part down and protecting the input source as well as the output load depending on the particular fault conditions. Inrush current limiting is included to slowly charge the input capacitor without interruption due to die heating, a problem encountered without the current limit foldback feature.
