7.8 VCC Voltage Supply

An external voltage can be applied to the VCC pin to power the internal logic circuitry. The voltage on the VCC pin should be between 3.05 V and 5.5 V and should be well regulated. When an external supply is not available, VCC must be connected to the DVDD pin of the device. When powered by the VCC, the internal logic blocks do not consume power from the VM supply rail - thereby reducing the power loss in the DRV8262. This is beneficial in high voltage applications, and when ambient temperature is high. Bypass the VCC pin to ground using a 0.1 μF ceramic capacitor.
