ATC9030

QC 3.0 Controller

ATC9030is a USB mobile device charger interface IC which implements the Qualcomm's QuickCharge 3.0 specification for adaptive voltage battery charging. It incorporates all necessaryfunctions to add Quick Charge 3.0 capability to traditional secondary-side feedback schemes.

ATC9030supports the full output voltage range of Quick Charge 3.0, including 200mV microstepped voltage levels from 3.6 V to 12 V (Class A) and up to 20 V (Class B). provides asuite of system level protection features protecting the power supply and connected PoweredDevice (PD) from excessive output voltages, secondary-side thermal overload, and faulty powerdelivery while adapter is unplugged. Additionally it allows the PD to remotely shutdown the powersupply through USB data lines. The shutdown type can be configured as either hysteretic orlatching.

ATC9030automatically detects whether a connected PD is Quick Charge 3.0 or Quick Charge 2.0capable before enabling output voltage adjustment. If a PD that is not compliant to Quick Charge2.0 or 3.0 is detected, the disables output voltage adjustment to ensure safe operationwith legacy 5 V only USB PDs.
