MAX6840

超低电压、SC70封装电压检测器及微处理器复位电路

MAX6832–MAX6840是微处理器(µP)监控电路,用于监视µP和数字系统中的低电压电源。用于+1.2V至+1.8V供电电路时无需任何外部元件和调节,可提供出色的电路可靠性和低廉的成本。\n\n 当VCC电源电压跌至门限以下或手工复位(/MR)被触发时,这些器件将触发复位。在VCC重新上升到复位门限以上或手动复位被清除之后,复位信号将在一个固定的延迟内继续保持有效。器件有5种不同的超时周期:70µs (电压监视器)、1.5ms、30ms、210ms和1.68s。不同复位门限适用于不同的电源电压。\n\n MAX6832/MAX6835/MAX6838具有推挽式、低电平 • 工厂预置复位门限,用于1.2V至1.8V标称电源\n• 低功耗:7.5µA (典型值)\n• 节省空间的3引脚或4引脚SC70封装\n• 工作温度范围内保证±2.5%的复位门限精度\n• 5种不同的超时周期:70µs (电压监视器)、1.5ms、30ms、210ms和1.68s\n• 3种复位输出配置\n• 推挽式/RESET\n• 推挽式RESET\n• 漏极开路/RESET\n\n\n• 保证复位输出有效至VCC =\n• 0.55V—低电平有效\n• 0.75V—高电平有效\n\n\n• 可调门限RESET输入选项\n• 手动复位输入\n• 不受VCC负向瞬变的影响\n• 引;
