CXDR75100监控电路监控微处理器和数字系统中的电源电压。CXDR7599/CXDR75100设计用于监测七种不同的电压；选择这些电压可有效监测1.8V、2.5V、3V、3.3V和5V电源电压水平。它们在通电、断电和断电状态下提供复位输出。通电时，内部计时器将断言的重置保持240ms。这将使微处理器保持重置状态，直到条件稳定。/RESET输出在VCCA低至1V时保持工作状态。CXDR7599提供有效的低复位信号（/RESET），而CXDR75100提供有效的高信号（复位）输出。CXDR7599/CXDR75100具有手动复位输入。手动复位功能非常有用，特别是当CXDR7599/CXDR75100工作的电路进入只能由用户检测的状态时。允许用户手动重置系统可以减少失控或锁定系统可能造成的损坏或危险。这些设备有SOT-143和SOT-23-5两个封装。

产品概述 返回TOP
The CXDR7599/CXDR75100 supervisory circuits monitor the power supply voltage in microprocessor and digital systems. The CXDR7599/CXDR75100 is designed to monitor seven different voltages; these voltages have been selected for the effective monitoring of 1.8V, 2.5V, 3V, 3.3V and 5V supply voltage levels.
They provide a reset output during power-up, power-down and brownout conditions. On power-up, an internal timer holds reset asserted for 240ms. This holds the microprocessor in a reset state until conditions have stabilized. The /RESET output remains operational with VCCas low as 1V. The CXDR7599 provides an active low reset signal (/RESET) while the CXDR75100 provides an active high signal (RESET) output.
The CXDR7599/CXDR75100 has a manual reset input. The manual reset function is very useful, especially if the circuit in which the CXDR7599/CXDR75100 is operating enters into a state that can only be detected by the user. Allowing the user to reset a system manually can reduce the damage or danger that could otherwise be caused by an out-of-control or locked system. The devices come in SOT-143 and SOT-23-5 packages.
