CXDR7590经济高效的系统监控集成电路数字和混合信号系统中监控VCC并在系统电源超出工作范围时提供警告信号必要时向主机处理器提供重置信号

CXDR7590是一种经济高效的系统监控集成电路（IC），设计用于在数字和混合信号系统中监控VCC，并在系统电源超出工作范围时提供警告信号，必要时向主机处理器提供重置信号。不需要外部组件。CXDR7590还提供手动复位输入。复位输出在VCC通过复位电压阈值的20μs内被激活。VCC上升到重置阈值以上后，重置保持激活状态。CXDR7590具有有效的低复位输出。CXDR7588的输出保证在VCC=1V下有效。CXDR7590的特点是在-40oC到125oC的温度下工作。CXDR7590经过优化，可排除VCC线路上的快速瞬态故障。7μA（VCC=3.3V）的低供电电流使这些设备适合于电池供电的应用。输出电压从1.7V到4.5V，增量为100mV。标准电压版本为2.30、2.63、2.93、3.08、4.0、4.38和4.63V。

The CXDR7590 is a cost-effective system supervisor Integrated Circuit (IC) designed to monitor VCC in digital and mixed signal systems and provide a warning signal when the system power supply is out of working range, and a reset signal to the host processor when necessary. No external components are required. The CXDR7590 also provides a manual reset input. The reset output is driven active within 20μsec of VCC falling through the reset voltage threshold. Reset is maintained active after VCC rises above the RESET threshold. The CXDR7590 has an active-low RESET output. The output of the CXDR7588 is guaranteed valid down to VCC=1V. The CXDR7590 is characterized for operation from -40o C to 125o C, junction temperature. The CXDR7590 is optimized to reject fast transient glitches on the VCC line. Low supply current of 7μA (VCC=3.3V) makes these devices suitable for battery powered applications. The output voltages range from 1.7V to 4.5V in 100mV increments. Standard voltage versions are 2.30, 2.63, 2.93, 3.08, 4.0, 4.38, and 4.63V.
