目录产品概述 返回TOP These circuits perform a single function: they assert a reset signal whenever the VCC supply voltage declines below a preset threshold, keeping it asserted for at least 220ms after VCC has risen above the reset threshold. Reset thresholds suitable for operation with a variety of supply voltages are available. The CXDR75103 have a push-pull and active-low RESET output. The reset comparator is designed to ignore fast transients on VCC, and the outputs are guaranteed to be in the correct logic state for VCC down to 1V. Low supply current makes the CXDR75103 ideal for use in portable equipment. The CXDR75103 are available in a SOT-143 packages.The CXDR75103 are microprocessor (μP) supervisory circuits used to monitor the power supplies in μP and digital systems. They provide excellent circuit reliability and low cost by eliminating external components and adjustments when used with +5V, +3.3V, +3.0V- powered circuits. The CXDR75103 also provides a debounced manual reset input产品特点 返回TOP „Precision Monitoring of +3V, +3.3V, and +5V Power-Supply Voltages „ Fully Specified Over Temperature „ Push-Pull Active-low RESET Output „ 220ms Min Power-On Reset Pulse Width „ 10μA Supply Current „ Guaranteed Reset Valid to VCC = +1V „ Power Supply Transient Immunity „ No External Components „ Manual Reset Input „ SOT-143 Package „ 2% Threshold Accuracy 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！
