产品概述 返回TOP
The CXDC65100/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 CXDC65100/A/B operate 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 CXDC65100/A/Bseries is available with three output stage versions :CXDC65100 push-pull active low output, CXDC65100A push-pull active high output and CXDC65100B open drain active low output. They are also designed to reject fast line transient glitches on Vcc. The CXDC65100/A/Bare come in a miniature SOT-23, SOT-23-5, SOT-89 packages.
