                                                                                                    PM8805TR is a IEEE 802.3bt PoE-PD interface with embedded dual active bridge in a 43 pin VFQFPN package. It is a system-in-package for smart power supply of PoE PD and it is applicable for power level up to 99.9W. It embeds: two active bridges and their driving circuitry, a charge pump to drive the high-side MOSFETs, the hot swap MOSFET and the interface compliant with IEEE 802.3bt. The device performs the physical layer classification, providing indication of successful PSE type identification. A 4-pair PSE is identified and information is available by dedicated matrix of Tx signals. It works with power either from the Ethernet cable or from an external power source such as a wall adapter, with possible prevalence of the auxiliary source with respect to the PoE. It is suitable to build the interface section of PoE switch mode power supplies targeting the highest conversion efficiency. It provides PGD signal that can be used to enable PWM controller, DC-DC converter or LED driver.
