CXDR75117 CXDR75118 also provides a debounced manual reset input. These circuits perform a single function: they assert a reset signal whenever the VCC supply voltage declines below a preset threshold

CXDR75117 CXDR75118 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 CXDR75117/CXDR75118 also provides a debounced manual reset input. 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 230ms after VCC has risen above the reset threshold. Reset thresholds suitable for operation with a variety of supply voltages are available. The CXDR75118L has an open-drain output stage, while the CXDR75117 have push-pull outputs. The CXDR75118’s open-drain RESET output requires a pull-up resistor that can be connected to a voltage higher than VCC. The CXDR75117 have an active-low RESET output, while the CXDR75117 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 CXDR75117/CXDR75118 ideal for use in portable equipment. The CXDR75117/CXDR75118 are available in a SOT-143, SC-70-5(SOT-353), SOT-23-5 packages
