Texas Instruments LM74500Q1EVM Controller Evaluation Module

Texas Instruments LM74500Q1EVM Controller Evaluation Module (EVM) helps designers evaluate the operation and performance of the LM74500-Q1, a reverse polarity protection controller. This evaluation module demonstrates how an N-channel power MOSFET can be used to realize input reverse voltage protection with a low IQ controller (LM74500-Q1). In this design scheme, the Texas Instruments LM74500-Q1 is combined with a MOSFET and used in series with a battery as a replacement of a traditional PFET based reverse-polarity protection circuitry.
