CXDR75108 CXDR75109具有开漏输出级,而CXDR75108具有推拉输出。CXDR75109L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。GCXDR75108具有激活的低复位输出,而CXDR75108具有激活的高复位输出。复位比较器被设计成忽略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CXDR75108 CXDR75109非常适合用于便携式设备。CXDR75108 CXDR75109有3针SOT-23、TO-92、SC-70-3(SOT-323)和SOT-89封装。CXDR75108 CXDR75109是微处理器(μP)监控电路,用于监控μP和数字系统中的电源。当与+5V,+3.3V,+3.0V供电的电路一起使用时,通过消除外部元件和调整,它们提供了卓越的电路可靠性和低成本。这些电路执行一个单一的功能:每当VCC电源电压下降到预设阈值以下时,它们就断言一个复位信号。适用于各种电源电压操作的重置阈值可用。

The CXDR75109L has an open-drain output stage, while the CXDR75108 have push-pull outputs. The CXDR75109L’s open-drain RESET output requires a pull-up resistor that can be connected to a voltage higher than VCC. The GCXDR75108 have an active-low RESET output, while the CXDR75108 has an active-high 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 CXDR75108 CXDR75109 ideal for use in portable equipment. The CXDR75108 CXDR75109 are available in 3-pin SOT-23, TO-92, SC-70-3(SOT-323) and SOT-89 packages The CXDR75108 CXDR75109 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. These circuits perform a single function: they assert a reset signal whenever the VCC supply voltage declines below a preset threshold. Reset thresholds suitable for operation with a variety of supply voltages are available.
