LM7480x-Q1 Ideal Diode Controller

Texas Instruments 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 over-voltage protection. The wide input supply of 3V to 65V allows protection and control of 12V and 24V automotive battery powered ECUs. The device can withstand and protect the loads from negative supply voltages down to –65V. 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) and overvoltage protection using HGATE control. The device features an adjustable over-voltage cut-off protection feature. The Texas Instruments LM7480x-Q1 controller can drive the external MOSFETs in Common Drain and Common Source configurations. With the Common Drain configuration of the power MOSFETs, the mid-point can be utilized for OR-ing designs using another ideal diode. The LM7480x-Q1 has a maximum voltage rating of 65V. The loads can be protected from extended over-voltage transients like 200V Unsuppressed Load Dumps in 24V Battery systems by configuring the device with external MOSFETs in Common Source topology.
