CXDR75128 CXDR75129开漏输出级活动低复位输出5V 3.3V 3.0V电源电路VCC电源电压下降到预设阈值以下时重置信号VCC上升到重置阈值以上时滞后使其保持为外部可编程延时发生器确定的延时断言

产品简介

The CXDR75129L has an open-drain output stage, while the CXDR75128 have push-pull outputs. The CXDR75129’s open-drain RESET output requires a pull-up resistor that can be connected to a voltage higher than VCC. The CXDR75128 have an active-low RESET output, while the CXDR75128 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 0.8V. Low supply current makes the CXDR75128/CXDR75129 ideal for use in portable equipment. The CXDR75128/CXDR75129 are available in 5-pin SOT23-5 or TSOT-23-5 packages.The CXDR75128/CXDR75129 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. These circuits perform a single function: they assert a reset signal whenever the VCC supply voltage declines below a preset threshold, with hysteresis keeping it asserted for time delay determined by externally programmable time delay generator after VCC has risen above the reset threshold. Reset thresholds suitable for operation with a variety of supply voltages are available.
