Vishay推出新的“V”低压电源选项

21ic讯 日前,Vishay Intertechnology, Inc.宣布,为其TSOP 红外系列接收器中的10种产品推出新的“V”低压电源选项,扩充其光电子产品组合,以满足电池供电的消费产品对更低工作电压的需求。在低至2V的电源电压和+5℃~+85℃的温度范围内工作时,V系列器件始终能够保持稳定的灵敏度等级。

在采用2节碱性电池的应用中,以160mA负载工作3小时,电池的典型放电曲线会从3V降到2.5V。这意味着只能在2.5V电压下工作的标准接收器将停止工作。而一个典型非线性电池的放电曲线能在电压降到2V之前让接收器再工作13小时,因此一个能在2V电压下工作的接收器能够将有用的电池寿命延长4倍以上。

Vishay的V系列产品的典型终端应用产品包括电池供电的小型手持系统,如数码相机、双向遥控器和3D眼镜等。为在电池供电系统中进一步节能,接收器还具有待机功能。

Vishay的TSOP系列红外接收器中有6种封装的10款型号提供V选项,包括:
• 采用cast封装的TSOP312…、TSOP313…和TSOP314…
• 采用MiniCast封装的TSOP38…和TSOP39…
• 采用模压封装的TSOP32…和TSOP34…
• 采用标准SMD封装的TSOP35…
• 采用Heimdall封装的TSOP75…
• 采用bugeye封装的TSOP85…
