UFCS (Universal Fast Charging Specification): The Universal Fast Charging Specification, also known as the Mobile Terminal Integrated Fast Charging Technology Specification, aims to solve the problem of various and incompatible charging protocols on the market, and provide consumers with a better user experience.UFCS is the first fast charging technology standard in China, released by the Telecommunications Terminal Industry Association, promoting green and low-carbon development in the industry and playing a role in energy conservation and environmental protection.

Previously, Nanxin Technology has launched two UFCS certified products:SC2155A&SC2101BIt supports multiple protection mechanisms such as overvoltage protection, undervoltage protection, and overcurrent protection, and can be widely used in product fields such as wall adapters, travel adapters, and power boards.Recently, Nanxin has once again launched a protocol chip - SC2201, adding another UFCS certified chip.

Tu Nan Xin has passed UFCS certification for products: SC2155A&SC2101B

Product Introduction

Recently, Nanxin has once again launched the SC2201 protocol chip, which has been certified by UFCS.

This protocol chip integrates functions such as BC1.2 detection, UFCS protocol reception and transmission, internal CRC, adaptive baud rate, response confirmation, automatic retry, and timer and counter. SC2201 adopts WLCSP-8; 1.572mm * 0.772mm high integration packaging. It can be widely used in mobile phones, tablets, and other fast charging devices.
