Description

The LM74681 Evaluation Module (LM74681EVM) helps designers evaluate the operation and performance of the LM74681 ideal diode bridge controller (12-pin DRR package). This evaluation module demonstrates how an N-channel power MOSFET driven by LM74681 can emulate a very-low forward voltage diode and helps powering up polarity agnostic systems with very low IQ during detection and classification phase in POE applications.
