目录产品概述 返回TOP The CXDR75111/CXDR75112 are microprocessor (μP) supervisory circuits used to monitor the power supplies in μP and digital systems. High- and Low- voltage thresholds can be adjusted independently, allowing for wide hysteresis. Voltage detection thresholds are accurate to 2%. These circuits perform a single function: they assert a reset signal whenever the VCC supply voltage declines below the low-voltage threshold, keeping it asserted for at least 140ms after VCC has risen above the high-voltage threshold. The CXDR75112L has an open-drain output stage, while the CXDR75111 have push-pull outputs. The GCXDR75112’s open-drain RESET output requires a pull-up resistor that can be connected to a voltage higher than VCC. The GCXDR75111 have an active-low RESET output, while the GCXDR75111 has an active-high RESET output. The reset comparator is designed to ignore fast transients on threshold input. The IC’s power supply is separate from the detector inputs, allowing the CXDR75111/CXDR75112 to be powered from a down-stream supply. Low supply current (4μA, typical) makes the CXDR75111/CXDR75112 ideal for use in portable equipment. The CXDR75111/CXDR75112 are available in SOT -23-5 packages.产品特点 返回TOP „ ±2.5% Voltage Threshold Accuracy „ Independently Adjustable High- and LowVoltage Thresholds „ Fully Specified Over Temperature „ Available in Three Output Configurations Push-Pull RESET Output (CXDR75111L) Push-Pull RESET Output (CXDR75111H) Open-Drain RESET Output (CXDR75112L) „ 140ms min Power-On Reset Pulse Width „ 4μA Supply Current „ Power Supply Transient Immunity „ SOT-23-5 Packages 应用范围 返回TOP „ Computers „ Controllers „ Intelligent Instruments „ Critical μP and μC Power Monitoring „ Portable / Battery-Powered Equipment „ Automotive 技术规格书（产品PDF) 返回TOP 需要详细的PDF规格书请扫一扫微信联系我们，还可以获得免费样品以及技术支持！
