CXDR7594低功耗微处理器监控电路监控系统电压从1.6V到5V。该设备执行一个单一功能：每当VCC电源电压低于其重置阈值时，它会断言重置信号。VCC上升到重置阈值以上后，重置输出在重置超时期间保持断言状态。复位超时是由电容器外部设置的，以提供更大的灵活性。
CXDR7594具有激活的高推拉复位输出。有绿色SC70-4（R）和SOT-143两种包装

产品概述 返回TOP
The CXDR7594 low-power micro-processor supervisor circuit monitors system voltages from 1.6V to 5V. This device performs a single function: it asserts a reset signal whenever the VCC supply voltage falls below its reset threshold. The reset output remains asserted for the reset timeout period after VCC rises above the reset threshold. The reset timeout is externally set by a capacitor to provide more flexibility.
The CXDR7594 has an active-high, push-pull reset output. It is available in Green SC70-4 (R) and SOT-143 packages. The CXDR7594 is specified over an ambient temperature range of -40℃ to +85℃.
