Note: This is a very simplified example of an application circuit. The function must be
1. Recommended for applications with microcontroller I/O voltage levels less than
2. Required for applications that do not provide a reverse battery protected BAT supply.
3. May be required for module level compliance with EMC specifications, but they are
4. Connect to the REF pin directly to GND to enable the internal 2.5 V voltage reference.
5. Optional. Defines SO signal voltage when the SO pin has failed as an open circuit.
Note: In case of an unused channel, the OUTx, NEGx, and POSx pins should be
