SNOSD17G October 2017 – December 2020 LM74700-Q1
The LM74700-Q1 is used with N-Channel MOSFET controller in a typical reverse polarity protection application. The schematic for the 12-V battery protection application is shown in Figure 10-1 where the LM74700-Q1 is used in series with a battery to drive the MOSFET Q1. The TVS is not required for the LM74700-Q1 to operate, but they are used to clamp the positive and negative voltage surges. The output capacitor COUT is recommended to protect the immediate output voltage collapse as a result of line disturbance.
