CXDR75124 CXDR75125手动复位输入可调手动复位时间低磁流变管脚持续拉过磁流变管脚中连接的电容器设置的脱胶延时后产生的电源电压操作的重置阈值可用

产品简介

These circuits perform a single function: they assert a reset signal whenever the VCC supply voltage declines below a preset threshold or manual reset is triggered, and keeping it asserted for time delay determined by adjustable time delay generator (CD pin) after VCC has risen above the reset threshold or manual reset is released. Reset thresholds suitable for operation with a variety of supply voltages are available. Manual reset is generated after pull low MR pin lastingly over deglitch time delay set by capacitor connected in MRDLY pin. The CXDR75125L has an open-drain output stage, while the CXDR75124 have push-pull outputs. The CXDR75125’s open-drain RESET output requires a pull-up resistor that can be connected to a voltage higher than VCC. 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 CXDR75124/CXDR75125 ideal for use in portable equipment. The CXDR75124/CXDR75125 are available in 6-pin SOT-23-6 and ADFN1.5X1.5-6 packages.The CXDR75124/CXDR75125 are microprocessor (μP) supervisory circuits used to monitor the power supplies in μP and digital systems. They provide excellent circuit reliability and low cost and adjustments when used with +5V, +3.3V, +3.0V- powered circuits.
