微功耗微处理器复位电路CXDC6598 CXDC6598A CXDC6598B推挽主动开漏有源低输出极低静态电流1.5μA

CXDC6598 CXDC6598A CXDC6598B设计用于监控mP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。CXDC6598 CXDC6598A CXDC6598B通过监测系统电源电压来操作。当输入电压降到固定阈值以下时，在Vcc上升到固定阈值以上后，设备在固定时间段内断言复位信号。CXDC6598 CXDC6598A CXDC6598B系列有三个输出级版本：CXDC6598推挽主动低输出、CXDC6598A推挽主动高输出和CXDC6598B
开漏有源低输出。它们也被设计用来抑制Vcc上的快速线路瞬态故障。

The CXDC6598/A/B are designed to monitor voltage supplies in mP and digital systems. The quiescent current is extremely low, typically 1.5 μA, making it ideal for portable battery operated equipment. The CXDC6598/A/B are operated by monitoring the system power supply voltage. When the input voltage drops below a fixed threshold, the device asserts a reset signal for a fixed time period after Vcc rises above the fixed threshold. The CXDC6598/A/B series are available with three output stage versions :CXDC6598 push-pull active low output,CXDC6598A pushpull active high output and CXDC6598B 

open drain active low output. They are also designed to reject fast line transient glitches on Vcc. The CXDC6598/A/B come in a miniature SOT-23, SOT-23-5, and SOT-89 packages
