Diodes Incorporated has launched two innovative USB Type-C Power Delivery (PD) 3.1 extended power range (EPR) sink controllers designed to enhance battery-powered devices.
The new controllers, AP33771C and AP33772S, are suitable for devices such as routers, wireless speakers, power banks, and power tools that utilize USB Type-C sockets for power sourcing. They facilitate the transition from proprietary charging ports and legacy USB connectors to standardized USB PD ports, enabling designers to create smaller applications that charge faster with fewer components. This makes the products particularly appealing to product designers, engineers, and manufacturers looking to improve efficiency in their battery-powered offerings.
Both controllers effectively manage DC power requests in USB Type-C equipped devices, supporting PD 3.1 EPR up to 140W and an adjustable voltage supply (AVS) up to 28V. This allows them to outperform competing devices that typically support AVS only up to 21V. The AP33771C is particularly flexible for systems lacking a microcontroller (MCU), providing multiple power profiles, including eight resistor-settable output voltage levels and current options. In contrast, the AP33772S features an I2C communications interface, allowing integration with host MCUs.
Additionally, both controllers come with built-in smart firmware designed for practical applications such as LED light indication, cable voltage drop compensation, and moisture detection. While the AP33771C requires no programming to activate these features, the AP33772S can be configured using I2C commands. They also include 34V tolerant CC pins, enhancing system protection against accidental shorts to the high-voltage VBUS. By supporting NMOS FETs for input voltage delivery, these controllers help reduce the bill of materials (BOM).
The AP33771C is offered in the compact W-DFN3030-14 (3mm x 3mm) package and AP33772S comes in the W-QFN4040-24 (4mm x 4mm) package, for further details you may click here.
Diodes Incorporated continues to lead the way in providing high-quality semiconductor solutions tailored for the evolving needs of battery-powered device applications, targeting engineers and manufacturers focused on innovation and efficiency.
