【应用】 国产ESD抑制器TPA1006L05C助力I²C总线接口静电防护,ESD能力高达±25KV
I²C总线接口广泛应用于各类电子产品中,MCU等控制芯片易收到从I2C接口引入的静电损伤,为提高产品可靠性和保护后端器件,通常会在I2C总线接口处增加ESD防护方案。
针对I²C总线接口的ESD防护方案,电安科技推出ESD抑制器TPA1006L05C,可提供双向防护,工作电压5.0V,最小击穿电压6.5V,反向漏电流0.2μA,峰值脉冲功率100W(8/20μs),ESD防护等级满足IEC61000-4-2标准±25kV(空气放电)/±22kV(接触放电),以下是TPA1006L05C的主要电气参数:
采用I²C通讯接口的电子产品大多都是5V供电系统,TPA1006L05C工作电压5V,根据IEC61000-4-2标准,可以提供高达±25kV(空气放电)/±22kV(接触放电)的ESD保护,根据IEC61000-4-5,可承受4A(8/20μs)的峰值脉冲电流,完全满足I2C通讯总线接口ESD防护应用需求。
I²C总线有三种数据传输速度:标准,快速模式和高速模式,其中高速模式支持3.4Mbit/s的传输速率,对ESD抑制器件的结电容提出了更高的要求,TPA1006L05C的结电容一般在0.3pF,能满足I²C总线数据通信的要求。
TPA1006L05C封装是DFN1006,相当于标准0402封装,整体尺寸小,可以节省产品内部PCB占用面积,同时提供双向ESD防护,以下是TPA1006L05C的典型应用原理图:
综上所述,ESD抑制器TPA1006L05C具有低结电容、高防静电能力、小尺寸封装的特性,相比国内外同类产品,交期成本更具优势,是电子产品中I²C接口保护器件的优选。
