CXDR75124 CXDR75125这些电路执行单一功能:每当VCC电源电压下降到预设阈值以下或触发手动复位时,它们断言复位信号,并在VCC上升到复位阈值以上或释放手动复位后,将其保持为由可调延时产生器(CD引脚)确定的延时断言。适用于各种电源电压操作的重置阈值可用。手动复位是在将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。CXDR75125L具有开漏输出级,而CXDR75124具有推拉输出。CXDR75125的开漏复位输出需要一个上拉电阻器,该电阻器可以连接到高于VCC的电压。复位比较器设计用于忽略VCC上的快速瞬变,并且输出保证在VCC低至1V的正确逻辑状态。低电源电流使CXDR75124/CXDR75125非常适合用于便携式设备。CXDR75124/CXDR75125有6针SOT-23-6和ADFN1.5X1.5-6两种封装。CXDR75124/CXDR75125是微处理器(μP)监控电路,用于监控μP和数字系统中的电源。它们提供出色的电路与+5V,+3.3V,+3.0V电源电路一起使用时的可靠性、低成本和调整

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.
