Abstract: In most electronic systems, it is important to monitor system voltages both to ensure that processors and other ICs remain reset during power-up, and to detect when brownout conditions occur. This monitoring minimizes code-execution problems, which corrupt memory or cause systems to execute improperly. In high-end systems, it is also critical to ensure proper sequencing of the many power supplies within these systems. Proper sequencing prevents latch-up conditions, which create system problems or damage important components such as microcontrollers (µCs), DSPs, ASICs, or microprocessors (µPs). Commonly, one or more supervisory products are needed to implement the proper sequencing and monitoring functions noted here. As the number of voltages continue to increase, the number of independent supervisory ICs also may increase. In addition to the number of discrete components, the level of complexity also increase as any changes to the sequencing order, delay timing, or the monitored thresholds levels requires significant changes. Additional information is also required such as exact voltage measurements from an ADC is also often useful in improving reliability in these high end complex systems. New programmable system management ICs such as the eeprom configurable MAX6870/MAX6871 provides a fully integrated solutions that offer this level of flexibility. 你所查询的应用笔记提供Acrobat PDF格式： APPLICATION NOTE 3456:Programmable System-Management IC Monitors and Sequences Requirements in Complex, Multivoltage Systems (PDF, 186kB) 免费Acrobat PDF阅读软件可从以下网站获得： http://chinese-s.adobe.com/products/acrobat/readstep2.html 相关型号   APP 3456: Jan 17, 2005 MAX6819 SOT23封装、电源排序器 完整的数据资料 (PDF, 528kB) 免费样品 MAX6820 SOT23封装、电源排序器 完整的数据资料 (PDF, 528kB) 免费样品 MAX6870 EEPROM可编程、六/四路电源排序器/监控电路，带有ADC 完整的数据资料 (PDF, 664kB) 免费样品 MAX6870EVKIT MAX6870、MAX6871、MAX6872、MAX6873、MAX6874、MAX6875评估系统/评估板 完整的数据资料 (PDF, 1.5MB) MAX6871 EEPROM可编程、六/四路电源排序器/监控电路，带有ADC 完整的数据资料 (PDF, 664kB) 免费样品 自动更新 需要自动接收最新发布的应用笔记吗？请订阅EE-Mail™ (English only)。 我们期待您的反馈！ 喜欢？不喜欢？有待改善？或为我们提供建议？请与我们联系 — 我们将根据您的意见或建议改善我们的工作。 网页评价或提供建议   下载，PDF格式 (186kB)  AN3456, AN 3456, APP3456, Appnote3456, Appnote 3456
