200毫秒重置脉冲宽度CXDR7592手动复位输入电源故障或电池电量低警告的电压监视器双重设输出25V阈值检测器电源故障警告电池电量不足检测或监测附加电源

CXDR7592微处理器监控电路降低了监控电源和监视微处理器活动所需的组件的复杂性和数量。与单独的集成电路或分立元件相比，它显著提高了系统的可靠性和准确性。CXDR7592提供电源监控电路，在通电、断电和断电时产生复位输出。复位输出在VCC低至1V时保持工作。
此外，还有一个1.25V阈值检测器，用于电源故障警告、电池电量不足检测或监测附加电源。还包括一个有效的低手动复位输入（/MR）。

The CXDR7592 microprocessor supervisory circuit reduces the complexity and number of components required to monitor power-supply and monitor microprocessor activity. It significantly improves system reliability and accuracy compared to separate ICs or discrete components.

 

The CXDR7592 provides power-supply monitoring circuitry that generates a reset output during power-up, power-down and brownout conditions. The reset output remains operational with V_CC as low as 1V.

 

In addition, there is a 1.25V threshold detector for power-fail warning, low-battery detection, or monitoring an additional power supply. An active-low manual-reset input (/MR) is also included.

 

The CXDR7592 is available in Green SOIC-8 package. It operates over an ambient temperature range of -40℃ to +85℃.
