Product Details
The STMicroelectronics PM8805 is a system-in-package for smart power supply of Power over Ethernet (PoE) Powered Devices (PD) and it is applicable for power level up to 99.9 W. 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 the indication of successful PSE type identification. A 4-pair PSE is identified and the information is available by a dedicated matrix of TX signals.
Programmable classification current with 3.3 ms delay.
Optional Auto class feature
Advanced energy-saving MPS timings
Two-step hot swap current protection: DC with 1 ms delay and short-circuit with 10 us delay.
Controlled pre-charge of the output capacitor
PGD signal (open drain) to enable an external PWM controller.
Thermal shutdown protection
