产品概述 返回TOPzUV嘉泰姆
The CXDR7591 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.zUV嘉泰姆
The CXDR7591 provides power-supply monitoring circuitry that generates a reset output during power-up, power-down and brownout conditions. The reset output remains operational with VCC as low as 1V. Independent watchdog monitoring circuitry is also provided. This is activated if the watchdog input has not been toggled within 1.6 seconds.zUV嘉泰姆
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.zUV嘉泰姆
The CXDR7591 is available in Green SOIC-8 package. The CXDR7591-S is available in both Green SOIC-8 and MSOP-8 packages. They operate over an ambient temperature range of -40℃</span> to +85℃</span>.zUV嘉泰姆
