Texas Instruments LM7472EVM Controller Evaluation Module (EVM)

Texas Instruments LM7472EVM Controller Evaluation Module (EVM) helps designers evaluate the operation and performance of the LM74720-Q1 and LM74722-Q1 ideal diode controllers in reverse battery protection applications. This evaluation module demonstrates how the Texas Instruments LM7472x-Q1 with integrated boost regulator for Low IQ and fast transient response controls two back-back N-channel power MOSFETs. It is done with an ideal diode MOSFET connected first, followed by a second MOSFET for switched output and power path cut-off.
