The LM74700-Q1 evaluation module (LM74700DDFEVM) assists designers to evaluate the operation and performance of the LM74700-Q1 ideal diode controller (8-pin DDF package). This evaluation module demonstrates how an N-channel power MOSFET can emulate a very-low forward voltage diode with low I_Q and low-leakage current flowing through the IC. In this design scheme, the LM74700-Q1 is combined with a MOSFET and used in series with a battery as a replacement for a Schottky diode and PFET, in reverse-polarity protection circuitry as shown in Figure 2-1. For more information on the LM74700-Q1 functional and electrical characteristics, see LM74700-Q1 Low I_Q reverse battery protection ideal diode controller.

This section describes the jumpers and connectors on the EVM, and how to properly connect, setup, and use the LM74700DDFEVM. Ensure the power supply is turned off while making connections on the board.
