Texas Instruments TPS3847085 18V 30nA 电压监视器
德州仪器 TPS3847085 18V 30nA 电压监视器是宽工作电压范围的超低电流器件,用于监控供电引脚电压。这些器件在每当 VCC 电源电压将至出厂微调的复位阈值电压以下时,置位一个低电平有效复位信号。在VCC 电压升至阈值电压以上后,复位输出会继续保持有效 20ms (最长)。380nA 的超低电流消耗结合 18V 的性能,使 TPS3847 成为低功耗和便携式应用的理想选择。TPS3847 具有精密的、经出厂微调的阈值电压,并能在极低功耗下工作。TPS3847 采用 5 引脚行业标准的 SOT-23 封装。特性
