MP8021

IEEE 802.3af/at/bt Compliant Powered Device with Power Monitor via I2C Interface; • IEEE 802.3af/at/bt Compliant\n• External MOSFET for Flexible Power Design\n• 100V Input Voltage (VIN) Rating\n• 13-Bit Analog-to-Digital Converter (ADC) for Power Monitor\n• 400kHz Isolated I2C interface\n• Power Monitor for Both Power over Ethernet (PoE) and Adapter\n• Mark Event Number Readback\n• Dual Power-Sourcing Equipment (PSE) or Adapter/PSE Hitless Fail-Over\n• Supports Adapter Priority Control\n• Minimum PSE Power-Up Level Setting\n• Automatic Maintain Power Signature (MPS)\n• Available in a TQFN-20 (5mmx5mm) Package\n;

The MP8021 is an IEEE 802.3af/at/bt compliant Power over Ethernet (PoE) powered device (PD). The device supports all the functions of IEEE 802.3af/at/bt, including detection, 5-event classification, inrush current (IINRUSH) control, and an external hot-swap MOSFET driver.\n\n During the start-up period, The MP8021 limits the hot-swap current below the inrush current limit. The device fully turns it on after the inrush period finishes. The MP8021 features an intelligent maintain power signature (MPS) function and input under-voltage lockout (UVLO) with a wide hysteresis.\n\n The integrated I2C interface can read back the mark event number and monitor the real-time power. The MP8021 can also set the power priority between dual-port PoE supplies or between the PoE and a DC auxiliary supply for seamless fail-over backup applications.\n\n The MP8021 is available in a TQFN-20 (5mmx5mm) package.\n\n
