Description

The LM7480x-Q1 ideal diode controller drives and controls external back to back N-Channel MOSFETs to emulate an ideal diode rectifier with power path ON/OFF control and overvoltage protection.

Key Features

  • 3-V to 65-V input range
  • Reverse input protection down to -65 V
  • Ideal diode operation with 10.5-mV A to C forward voltage drop regulation (LM74800-Q1)
  • Low reverse detection threshold (-4.5 mV) with fast response (0.5 µs)
  • 20-mA peak gate (DGATE) turnon current
  • 2.6-A peak DGATE turnoff current
  • Adjustable overvoltage protection
  • Low 2.87-µA shutdown current (EN/UVLO=Low)
  • Meets automotive ISO7637 transient requirements with a suitable TVS diode
  • Available in space saving 12-Pin WSON package

Applications

  • Active ORing for redundant power
