DC-Motor Controller
3.2 Higher VCC Loads and higher Ambient Temperatures
For higher power consumption caused by higher VBAT or higher ambient temperatures, an external
regulator transistor can bring the main power consumption which is caused by regulator, outside of the
MLX81100 - so maximum chip temperature can be decreased to meet application needs.

3.3 High Side Reverse Polarity Protection
A high side full bridge reverse polarity protection can also be realised using the below schematics.
