SNOU177 December 2020 LM74700-Q1
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 IQ 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.
