LM7481/LM7481-Q1 Ideal Diode Controllers

Texas Instruments LM7481/LM7481-Q1 Ideal Diode Controllers offer active rectification and an adjustable over-voltage cut-off protection feature for load dump protection. The LM7481/LM7481-Q1 drives and controls external back-to-back N-channel MOSFETs to emulate an ideal diode rectifier with power path ON/OFF control and over-voltage protection. The device offers a wide input supply of 3V to 65V, allowing protection and control of 12V and 24V automotive battery-powered ECUs. The LM7481/LM7481-Q1 can withstand and protect the loads from negative supply voltages down to –65V.
