To make the design of the power supply portions of all powered devices simpler, the PM8800ATR includes a current mode PWM controller and a widely used power over Ethernet (PoE) interface. The IEEE 802.3af-required functions of detection, classification, under-voltage lockout (UVLO), and in-rush current restriction are all included in the PoE interface.

• Flexible in-rush current cap

  
  

• Programmable current for categorization

  
  

• Up to 800 mA of programmable DC current limit

  
  

• Start-up bias regulator for high voltage

  
  

• Thermal shut-off safeguards

  
  

• The pulse width modulator in current mode

  
  

• A frequency-programmable oscillator
