Description

The LM74930-Q1 Evaluation Module (LM74930Q1EVM) helps designers evaluate the operation and performance of the LM74930-Q1 ideal diode controller with power path ON/OFF control, overcurrent, short-circuit and overvoltage protection. The wide input supply of LM74930-Q1, 4V to 65V, allows protection and control of 12-V and 24-V automotive battery powered ECUs. The LM74930-Q1 can drive back-to-back external N-Channel MOSFETs connected in common source topology to realize surge stopper functionality. With first MOSFET in the power path, the device allows load disconnect (ON/OFF control) in case of overcurrent and surge/overvoltage events using HGATE control. An integrated ideal diode controller (DGATE) drives the second MOSFET to replace a Schottky diode for reverse input protection and output voltage holdup.
