CY2813-USB Type-C Charger ID with QC 2.0 Legacy


CY2813-USB Type-C Charger ID with QC 2.0 and Legacy DataSheet

GENERAL DESCRIPTION
CY2813 is an auto identification chip of different charger types including Type-C, QC 2.0 Class A, BC
1.2 DCP modes, and legacy. The detection procedure firstly performs Type-C detection(for
CY2813-14L and CY2813-10L) based on USB Type-C specification v1.1 for Downstream Facing
Port. Meanwhile, low power mode is designed(CY2813-14L) for power bank application. And then,
USB BC 1.2 DCP mode is enabled. After that, the Legacy (500mA USB 2.0, 900mA USB 3.0, 2A for
D+/D- at 2.7V) detection is completed.
In addition, the QC2.0 detection is implemented with class A or B capability, where Vbus can support
5V, 9V, 12V(for class A and B) or 20V (for class B only) according to QC 2.0 protocol handshake
results. If QC2.0 device is absent, the detection procedure will go back and stay at Legacy mode until
cable is disconnected. CY2813 covers most of the popular fast charging mechanisms including
emerging Type-C connector and provide customers with better user’s experience for portable
devices, especially mobile phones and tablet.
