LTC2935 - 具电源故障输出、可选门限的超低功率监控器
LTC®2935 超低功率电压监视器提供了系统初始化、电源故障报警和复位发生功能。低静态电流 (典型值为 500nA) 使 LTC2935 成为电池供电型应用的理想选择。
3 个二进制门限选择输入负责配置 8 种集成复位门限之一，范圍從 1.6V 至 3.45V (以预定的递增梯级)。一个“即将出现低电压条件”的预警将在电源故障输出端 (PFO) 上提供，它的门限在配置复位门限之上。监控电路负责监视 VCC，并在 VCC 降至配置复位门限以下时把 RST 拉至低电平。当 VCC 从一个低于门限的条件逐渐上升时，一个内部复位定时器将在超过复位门限达 5% 之后被起动。一个 200ms 的复位超时延迟了 RST 输出的返回至高态。一个与 MR 输入相连的按钮开关通常用于强制执行手动复位。输出 RST 和 PFO 存在于开路漏极 (LTC2935-1/LTC2935-3) 或有源上拉 (LTC2935-2/LTC2935-4) 电路。工作温度范围为 -40ºC 至 85ºC。
