Texas Instruments LM74800EVM-CD Evaluation Module (EVM)
Texas Instruments LM74800EVM-CD Evaluation Module (EVM) helps designers evaluate the operation and performance of the LM7480-Q1 ideal diode controllers (LM74800QDRR and LM74801QDRR) in reverse battery protection applications. The Texas Instruments LM74800EVM-CD demonstrates how LM7480-Q1 controls two back-back N-channel power MOSFETs with ideal diode MOSFET connected first, followed by the second MOSFET for switched output and power path cut-off.
