Texas Instruments LM74800EVM-CS Controller Evaluation Module

Texas Instruments LM74800EVM-CS Controller Evaluation Module (EVM) helps designers evaluate the operation and performance of the LM74800-Q1, an ideal diode controller with switched output. The LM7480x-Q1 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. The Texas Instruments LM74800EVM-CS demonstrates how the LM74800-Q1, along with two back-to-back N-Channel MOSFETs configured in common-source topology, can provide 200V unsuppressed load dump protection with reverse battery protection to the downstream circuit. The first gate drive HGATE controls an external N-channel MOSFET to turn off or clamp output voltage to an acceptable safe level. The second gate drive DGATE controls another external N-Channel MOSFET to emulate an ideal diode.
