Microprocessor Supervisory Circuit

SGM803、SGM809和SGM810是集成的微处理器监控器件，与使用单个IC或分立元件的设计相比，这种集成设计能够提高系统的稳定性和准确性。\n这些器件能够在上电、断电，甚至电压降低导致的欠压条件下进行复位。即使当VCC降至1V，复位输出依然能够工作。在上电状态下，内部定时器会保持240ms的复位断言，确保微处理器在条件稳定之前保持复位状态。\nSGM803具有开漏RESET输出，需要通过一个电阻上拉至VCC。而SGM809和SGM810则都具有推挽RESET输出。所有这些器件都提供了八个复位阈值电压选项，适用于1.8V、2.5V、3V、3.3V和5V的电压监控。\n此外，这些器件还具有出 • MAX803/MAX809/MAX810 和 ADM803/ADM809/ADM810 的卓越升级\n• 高精度固定检测选项：1.8V、2.5V、3V、3.3V 和 5V\n• 低电流消耗：13μA（典型值）\n• 150ms（最小值）上电复位\n• 复位输出选项：\n开漏复位输出：SGM803\n推挽复位输出：SGM809\n推挽复位输出：SGM810\n• 复位断言低至 1V VCC\n• -40℃ 至 +125℃ 工作温度范围\n• 采用绿色 SOT-23-3 和 SOT-23 封装;

Low Power Microprocessor Supervisory Circuit

GENERAL DESCRIPTION The SGM803B, SGM809B and SGM810B are integrated microprocessor supervisory devices which can be reset under power-up, power-down or even voltage reduction brownout conditions. When VCC is as low as 1V, the reset output can still operate. On the power-on state, the interna
