PM8805TR

IEEE 802.3bt PoE-PD interface with embedded dual active bridge

ECCN USEAR99
ECCN EUNEC
Packing TypeTape And Reel
RoHs compliantEcopack2
GradeIndustrial
Package NameQFN 8x8x1 43L P 0.5 6 Dice pad

The 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...

Key features
  • Dual active bridge, hot swap MOSFET and PoE-PD interface in a system-in-package
  • 100 V N-ch MOSFETs with 0.2 Ω total path resistance for each active bridge
  • 100 V, 0.1 Ω high-side N-ch hot swap MOSFET
  • PoE-PD single-signature interface compliant with IEEE 802.3bt / at / af
  • Supports 4-pair PoE applications
  • Supports 12 V auxiliary sources
  • Identifies which kind of PSE (standard or legacy) is connected with and provides successful IEEE802.3bt / at / af classification indication as a combination of the T0, T1 and T2 signals (open drain)
  • Smart operational modes
  • Programmable classification current with 3.3 ms delay
  • Optional Autoclass feature
  • Advanced energy-saving MPS timings
  • Two-step hot swap current protection: DC with 1 ms delay and short-circuit with 10 μs delay
  • Controlled pre-charge of the output capacitor
  • PGD signal (open drain) to enable an external PWM controller
  • Thermal shutdown protection
