تراشه شارژ سریع CHY103D پکیج SO-8

Introduction

CHY103 is a USB interface IC that supports Class A and Class B of the Quick Charge 3.0 specification. It includes features that protect the power supply and its connected Powered Device (PD) from excessive output voltages, secondary-side thermal overload, and faulty power delivery while adapter is unplugged.

The CHY103 interface IC automatically detects whether a connected PD is Quick Charge 3.0 or Quick Charge 2.0 capable before enabling output voltage adjustment. If a PD that is not compliant to Quick Charge 2.0 or 3.0 is detected, the CHY103 disables output voltage adjustment to ensure safe operation with legacy 5 V-only USB PDs.
