Texas Instruments LM74681EVM Evaluation Module
Texas Instruments LM74681EVM Evaluation Module allows users to evaluate the LM74681 ideal diode bridge controller in a 12-pin DRR package. The LM74681 100V ideal diode bridge controller drives a MOSFET bridge, enabling efficient low-loss bridge rectifier solutions in Power over Ethernet (PoE) applications. The TI LM74681EVM evaluation module demonstrates how an N-channel power MOSFET driven by LM74681 can imitate a very-low forward voltage diode and help power up polarity agnostic systems with very low IQ during detection and classification phase in POE applications.
Features
