说明

MAX4995A/MAX4995AF/MAX4995AL/MAX4995B/MAX4995C系列可编程限流开关具有内部限流特性,可避免主器件由于负载故障而损坏。这些模拟开关均具有130mΩ (典型值)的低导通电阻以及+1.7V至+5.5V的输入电压范围。器件可确保50mA至600mA的电流限制,非常适合SDIO (可靠的数字输入/输出)以及其它负载切换等应用。

该系列中的每款开关可根据不同选择提供不同的过流操作。MAX4995A/MAX4995AF/MAX4995AL进入自动重试模式、MAX4995B闭锁开关、MAX4995C将器件置于连续电流限制模式。其它的安全特性包括热关断以防止过热、以及反向电流抑制以防止电流流回源端。

MAX4995A/MAX4995AF/MAX4995AL/MAX4995B/MAX4995C提供纤小的10引脚、1.4mm x 1.8mm UTQFN封装、6引脚SOT23封装或8引脚、2mm x 2mm TDFN封装,工作在-40°C至+125°C扩展级温度范围。
