The USB-C solution designed for optimizing universal product charging is called Power Delivery (PD).
As part of the overall USB standard, this specification can coordinate chargers and powered devices to determine the appropriate voltage levels and power configurations. This allows the charger to deliver the maximum possible power, enabling faster charging for the device.
However, current consumer devices and home appliances still require dedicated chargers or adapters. System manufacturers can leverage USB Type-C PD chargers from smartphones and laptops to power the next generation of consumer devices, further reducing electronic waste and achieving corporate social responsibility goals. Therefore, incorporating USB PD sink controllers to enable USB Type-C PD functionality in next-generation devices has become a key design standard for system designers.
This coordination and control require the use of sink controller ICs, such as the DIODES from Diodes Incorporated.AP33771These controllers comply with the PD3.0 specification and are part of Diodes' extensive range of USB PD solutions.
Diodes Incorporated designs these controllers for home appliances and wireless power tools, offering a flexible and user-friendly solution. The AP33771 operates within a voltage range of 3.3V to 21V and can deliver up to 100W of power.
The AP33771 uses a simple pin-driven method to set the required voltage and power, while still offering the flexibility to choose from eight outputs and ten power levels to meet various customer needs.
