ZHCSWR1H December 2009 – July 2024 DRV8412
PRODUCTION DATA
The DRV83x2 requires a 12V power supply for GVDD and VDD pins. The total supply current is relatively low at room temperature (less than 50mA), 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 12V guard rings. TI recommends designing the 12V power supply with a current capability at least 5-10% of the load current, and no less than 100mA for the device performance across all temperature ranges.
