模拟电子 LTC1099基于PC的数据采集板实现
A complete design for a data acquisition card for the IBM PC is detailed in this application note. Additionally, C language code is provided to allow sampling of data at speed of more than 20kHz. The speed limitation is strictly based on the execution speed of the "C" data acquisition loop. A "Tur ...
电源技术 DN465 超低功耗升压转换器
 
Industrial remote monitoring systems and keep-alivecircuits spend most of their time in standby mode. Manyof these systems also depend on battery power, so powersupply effi ciency in standby state is very important tomaximize battery life. The LT®8410/-1 high effi ciencyboost converte ...
电源技术 DN457宽输入电压范围同步降压稳压器
 
The LTC®3610 is a high power monolithic synchronousstep-down DC/DC regulator that can deliver up to 12Aof continuous output current from a 4V to 24V (28Vmaximum) input supply. It is a member of a high currentmonolithic regulator family (see Table 1) that featuresintegrated low RDS(ON) ...
电源技术 LTC4099 USB电源管理和电池充电
 
The LTC®4099 high effi ciency USB power manager andLi-Ion/Polymer battery charger seamlessly managespower distribution from multiple sources in portableapplications. It is differentiated from other USB powermanagers by its bidirectional I2C port that allows the hostmicroprocessor to c ...
电源技术 LTC1325电池管理IC的使用
 
For a variety of reasons, it is desirable to charge batteriesas rapidly as possible. At the same time, overchargingmust be limited to prolong battery life. Such limitation ofovercharging depends on factors such as the choice ofcharge termination technique and the use of multi-rate/multi-s ...
电源技术 电网现场作业管理系统的信息化设计
为了改变目前电网现场作业管理的变电巡检、变电检修试验、输电线路巡检检修等管理系统各自独立运行,信息不能共享,功能、效率受限,建设和维护成本高的现状,提出了采用B/S+C/S构架模式,将各现场作业管理模块和生产MIS(管理系统)集成为一体的现场作业管理系统的设计方案,做到各子系统和生产MIS软硬资源共享,做到同一 ...

HT47R20A-1时基(Time Base)使用介绍
HT47 系列单片机的时基可提供一个周期性超时时间周期以产生规则性的内部中断。时基的时钟来源可由掩膜选择设定为WDT 时钟、RTC 时钟或指令时钟(系统时钟/4);其超时时间范围可由掩膜选择设定为“时钟来源”/212~“时钟来源”/215。如果时基发生超时现象,则其对应的中断请求标志(TBF ...
