2.3.2 LM7480-Q1

The LM7480-Q1 ideal diode controller drives and controls external back to back N-channel MOSFETs to emulate an ideal diode rectifier with power path ON and OFF control and overvoltage protection. The wide input supply of 3 V to 65 V allows protection and control of 12-V and 24-V supply rails. An integrated ideal diode controller (DGATE) drives the first MOSFET to replace a Schottky diode for reverse input protection and output voltage holdup. With a second MOSFET in the power path the device allows load disconnect (ON and OFF control) and overvoltage protection using HGATE control. The device features an adjustable overvoltage cutoff protection feature.
