LT4321 PoE Ideal Diode Bridge Controller - Video Product Brief

Alison Steer - Product Marketing Manager Sep 11th 2014
  The LT®4321 is a dual ideal diode bridge controller that enables a Power over Ethernet (PoE) powered device (PD) to receive power in either voltage polarity from RJ-45 data pairs, spare pairs, or both. The LT4321 and eight N-channel MOSFETs replace the eight diodes in a passive PoE rectifier bridge. The LT4321 ...

LT4320 Ideal Diode Bridge Controller - Video Product Brief

Alison Steer - Product Marketing Manager Sep 11th 2014
  The LT®4320/LT4320-1 are ideal diode bridge controllers that drive four N-channel MOSFETs, supporting voltage rectification from DC to 600Hz typical. By maximizing available voltage and reducing power dissipation (see thermograph comparison below), the ideal diode bridge simplifies power supply design and reduces ...
