PRODUCTION DATA
The DRV83x2 require a 12-V power supply for GVDD and VDD pins. The total supply current is pretty low at room temp (less than 50 mA), but the current could increase significantly when the device temperature goes too high (for example, above 125°C), especially at heavy load conditions due to substrate current collection by 12-V guard rings. So it is recommended to design the 12-V power supply with current capability at least 5-10% of your load current and no less than 100 mA to assure the device performance across all temperature range.
