CXDC65101 CXDC65101A CXDC65101B设计用于监测μP和数字系统中的电压供应。静态电流极低，通常为1.5μA，是便携式电池驱动设备的理想选择。CXDC65101/A/B通过监测系统电源电压来工作。当输入电压降到固定阈值以下或当主张手动复位时，设备在Vcc上升到固定阈值以上或解除手动复位后的固定时间段内断言复位信号。CXDC65101/A/B系列提供三个输出级版本：CXDC65101推拉激活低输出、CXDC65101A推拉激活高输出和CXDC65101B打开漏极激活低输出。CXDC65101/A/Balso有一个解除警告的手动复位输入，用于覆盖复位监视器。它们也被设计用来抑制Vcc上的快速线路瞬态故障

产品概述 返回TOP
The CXDC65101/A/B are designed to monitor voltage supplies in μP and digital systems. The quiescent current is extremely low, typically 1.5 μA, making it ideal for portable battery operated equipment. The CXDC65101/A/B operate by monitoring the system power supply voltage. When the input voltage drops below a fixed threshold or whenever manual reset is asserted, the device asserts a reset signal for a fixed time period after Vcc rises above the fixed threshold or manual reset is deasserted. The CXDC65101/A/Bseries is available with three output stage versions:CXDC65101 pushpull active low output, CXDC65101Apush-pull active high output and CXDC65101Bopen drain active low output. The CXDC65101/A/Balso have a debounced manual reset input that is provided to override the reset monitor. They are also designed to reject fast line transient glitches on Vcc. The CXDC65101/A/Bare come in a miniature SOT-23-5 package.
