SY6121 Sample Application
General Description

SY6121 is an iPhone Lightning data line control IC with high speed, ultra-low power loss and high noise resistance, and supports charging and data transmission of Apple devices. It has high integration, few peripheral components, simple circuit, and high stability and compatibility. The original application solution can be applied to Micro USB & Lightning 2-in-1 data cable. The device and its external MOS remain within a safe range even if Micro USB uses QC or other quick charge protocols and thus generates high voltage higher than 9V. SY6121 is available in a SOT23-6 package.
