9 Power Supply Recommendations

The TLC6C5712-Q1 device is qualified for automotive applications. Because of voltage-level limitations, the device requires a first-stage power supply to provide LED and device power. VCC and V(SENSE) voltages can be provided by the same voltage supply or independent voltage supplies. The supply voltage range is specified in Recommended Operating Conditions.
