    Key features
    • Features of the PM8805 PoE-PD interface:
      • System in package integrating a double active bridge, a hot-swap MOSFET and a PoE-PD
      • Supports legacy high power, 4-pair applications
      • 100 V N-ch MOSFETs with 0.2 Ω total path resistance for each active bridge
      • Identifies which kind of PSE (standard or legacy) is connected to, and provides successful IEEE802.3 af /at /bt classification indication as combination of the T0, T1 and T2 signals (open drain)
      • Smart operational mode selection through the STBY, FAUX and RAUX control signals
      • QFN 56 8x8mm package with 43 pins and 6 exposed pads
    • Features of the PM8804 PWM controller:
      • PWM peak current mode controller
      • Input operating voltage up to 75 V
      • Internal high voltage start up regulator with 20 mA capability
      • Programmable fixed frequency up to 1 Mhz
      • Soft start up with adjustable time
      • Soft turn off (optionally disabled)
      • Dual 1 APK, low side complementary gate drivers
      • GATE2 optionally turned off for reduced consumption
      • 80% maximum duty cycle with internal slope compensation
      • QFN 16 3x3mm package with exposed pad
