【应用】单节锂离子电池充电芯片HM5068用于智能手机，兼容不同手机型号、品牌和不同充电协议、充电速率
随着互联网和嵌入式技术的不断发展，智能手机走进千家万户，成为人们生产和生活中必不可少的通讯工具，此外，用户还可以根据自己的需求和偏好下载相应的应用程序，满足自身在社交、游戏、新闻、购物、音乐、视频、导航等方面的需求。
挑战
智能手机大多使用锂电池供电，电容量通常在1000mAh~5000mAh之间，电容量越大，待机的时间也相应越长。智能手机的尺寸和重量限制使得智能手机的电容量有限，因此，只有克服当前智能手机充电电压不稳定、充电效率低、电池寿命短和存在安全隐患的问题，最大限度的提高电池充电电路的能效和安全性，才能提高用户的使用体验。
解决方案和采用技术
智能手机支持视频、游戏、导航等功能，这意味着手机电路中的元器件工作压力大，对充电器件的要求高，能够适应高温的工作环境，保证充电系统的正常工作。虹茂半导体提出了基于HM5068的智能手机电池充电管理应用方案，HM5068是一款高集成度、高性价比的单节锂离子电池充电芯片，采用1.5MHz开关频率的降压型PWM控制，支持工作温度范围-40℃~85℃，可以兼容不同的手机型号和品牌，支持不同的充电协议和充电速率。
在充电效率方面，HM5068支持最大2.5A的充电电流，±6%的充电电流精度，当电池电压掉到再充电阈值以下，芯片将自动对电池再充电。支持涓流、恒流和恒压三段式充电，可以精确掌控充电状态、保护电池寿命、提高充电效率和节省电能，能够高效而稳定地传输电流和电压，以确保充电时间和充电效率的最大化
在充电安全性方面，HM5068时内部设有智能温控，当芯片内部温度过高，芯片会自动调节占空比降低充电电流，保证芯片温升不会太高，HM5068支持过温保护、电池温度检测，杜绝充电升温带来的安全隐患，HM5068还内置防倒灌功能，支持逐周期过流保护、输入电源去除自动进入休眠状态、10 小时定时关机功能，防止用户的智能手机设备出现过充导致的损坏和事故，保障智能手机用户的生命和财产安全。
成果与效益
虹茂半导体推出的智能手机充电应用方案，弥补了智能手机在锂电池充电过程中的功能缺陷，具有高效稳定、安全性高、兼容性强和智能化的特点，不仅为用户的设备提供了高效而稳定的充电服务，而且更好地保护了锂电池和智能手机设备。
