Overview

The LM749x0-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 with overcurrent and overvoltage protection. The wide input supply of 3 V to 65 V allows protection and control of 12-V and 24-V automotive battery powered ECUs. The device can withstand and protect the loads from negative supply voltages down to -65 V. 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/OFF control) in case of overcurrent and overvoltage events using HGATE control. The device has integrated current sense amplifier which provides accurate current monitoring with adjustable overcurrent and short circuit thresholds. The device features an adjustable overvoltage cut-off protection feature. The device features a SLEEP mode which enables ultra-low quiescent current consumption (6 μA) and at the same time providing refresh current to the always ON loads when vehicle is in the parking state. The LM749x0-Q1 has a maximum voltage rating of 65 V.
