【选型】力特自恢复保险丝用于车载77G电动尾门雷达电源输入过流防护设计,待机功耗仅0.171W
为避免车载77G电动尾门雷达电源输入因负载短路异常造成燃烧风险,一般在电源输入加一颗自恢复保险丝做过流保护设计,选型因素参考如下:额定工作电压:车载12V蓄电池供电,一般以2倍过压考量,建议选择耐压至少24VDC自恢复保险丝设计更安全;额定工作电流:一般与负载功率大小相关,同时考虑高温对自恢复保险丝影响严重,一般要求在高温60℃~70℃条件下保持电流至少1A;低待机功耗,通过AEC-Q200认证。
针对如上需求,推荐选择LITTELFUSE(力特)自恢复保险丝ASMDC185F/33 ,订单料号RF4575-000,2920封装,最大额定工作电压33VDC,常温25℃下保持电流1.85A,在70℃条件下保持电流1.04A,可承受最大故障电流40A,工作温度范围-40℃~85℃,通过AEC-Q200认证,典型电性参数参考如下图1所示。
图1:Littelfuse(力特)自恢复保险丝RF4575-000典型电性参数
推荐理由如下:
低待机功耗:可以通过计算得出,利用P=Ihold*Ihold*R得出,其中自恢复保险丝保持电流Ihold为1.85A,Rmin=0.05Ω,Rmax=0.15Ω,其中Ihold、Rmin和Rmax可通过图1中电性参数表格获取,带入公式得到Pmin≈0.171(W),Pmax≈0.513(W),即待机状态时的功耗为0.171W~0.513W。
通过AEC-200认证,满足车规级认证要求。
市面上有成熟应用,产品性能得到验证。

自恢复保险丝(PTC)的ITRIP电流的意义是什么?
Itrip可以叫做跳变电流,就是指电流超过该值时,电阻会出现大幅增加。其作为自恢复保险丝特有的重要参数,在设计选型时要格外重视。

如何为汽车电动车窗控制开关选择一款汽车级自恢复保险丝实现瞬时过载电流保护?
汽车电动车窗的控制开关接触瞬间会有很大的瞬时峰值电流,约300mA~500mA,持续时间约50ms以内,仅靠电阻无法做到快速响应保护,故设计电路需要再加一级保护,在电源线上串接一颗额定电压30VDC、保持电流Ihold为0.1A,跳闸电流Istrip为0.25A的littelfuse可恢复保险丝microASMD010F,实现瞬时过载电流保护,让控制系统实现高可靠性。

【应用】自恢复型保险丝PTC 16R600G应用于车载加热杯电源部分,跳闸快速,安全无铅
本文主要是给车载加热杯电源部分选择合适的保险丝。鉴于加热杯属于消费电子类产品,选择熔断型保险丝会增加售后成本,所以推荐选择PTC自恢复型保险丝。从加热杯的主要功能可以得知,工作温度为60℃左右。littelfuse 16R600G较为合适。16R600G的工作电压为16V,也满足电源电路工作电压为12V的条件。且在正常工作状态下,电阻仅为0.028欧姆,对电路影响小。

【选型】自恢复保险丝1812L110/33MR用于工业级3D视觉相机电源输入过流防护设计,待机状态功耗仅0.0726W
为避免工业级3D视觉相机电源输入因负载短路异常造成燃烧风险,一般在电源输入加一颗自恢复保险丝做过流保护设计,推荐选择Littelfuse(力特)自恢复保险丝1812L110/33MR ,1812封装,最大额定工作电压33VDC,常温25℃下保持电流1.1A,在50℃条件下保持电流830mA,可承受最大故障电流20A。
