Key features
  • System in package including a dual active bridge, a hot swap MOSFET and a PoE-PD interface
  • Robust 100V N-ch MOSFETs with 0.2 Ω total path resistance for each active bridge
  • Robust 100 V, 0.1 Ω high side N-ch hot swap MOSFET
  • PoE-PD single-signature interface compliant with IEEE 802.3bt
  • Detection and support of high power, 4-pair applications
  • Identifies which kind of PSE (standard or legacy) it is connected with, and provides successful IEEE 802.3af/at/bt classification indication through combination of the T0, T1 and T2 signals (open drain)
  • Programmable classification current with 3.3 ms delay
  • Advanced energy-saving MPS timings
  • Two step hot swap current protection: DC with 1 ms delay and overload with 10 µs delay
  • Startup phase (pre-charge of the output capacitor), performed using an internally limited current source
  • PGD signal (open drain) to enable an external PWM controller
  • Thermal shutdown protection
  • RoHS compliant
  • WEEE compliant
