Power-Supply Monitor with Reset

General Description The MAX709 provides a system reset during power-up, power-down, and brownout conditions. When VCC falls below the reset threshold, RESET goes low and holds the µP in reset for 140ms min after VCC rises above the threshold. The RESET output is guaranteed to be in the correct

带复位功能的电源监视器

MAX709在上电、关断和掉电情况下提供系统复位。当VCC低于复位阈值时，RESET变为低电平，并在VCC上升到阈值以上后将µP保持复位状态至少140ms。\n\n 当VCC低至1V时，RESET输出可保证处于正确状态。当与+5V、+3.3V或+3V供电系统一起使用时，MAX709它们无需外部元件，也不用进行调整，可实现非常可靠的低成本电路。MAX709采用8引脚DIP、µMAX®和SO封装。\n\n   • +5V、+3.3V和+3V版本\n\n• 无需外部元件\n\n• 低成本\n\n• 精密关断复位阈值\n\n• 140ms上电复位延迟（最小值）\n\n• 不受快速负VCC瞬变的影响\n\n• 8引脚DIP、µMAX和SO封装\n\n• 低电源电流：\n• 35µA - MAX709R/S/T\n\n• 65µA - MAX709L/M;
