SNOSDB7 December 2020 LM74500-Q1
PRODUCTION DATA
The LM74500-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 9-4 where the LM74500-Q1 is used to drive the MOSFET Q1 in series with a battery. The TVS is not required for the LM74500-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.
