CXDR75119 is a manual reset IC used in μP and digital systems. They provide excellent circuit reliability and low cost. These circuits perform a single function: they assert a reset signal whenever manual reset is triggered. Manual reset is generated after pull low MR pin lastingly over deglitch time delay set by capacitor connected in MRDLY pin. The CXDR75119 has an open-drain output stage. The 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 2.2V. Low supply current makes the CXDR75119 ideal for use in portable equipment. The CXDR75119 is available in ADFN1.5X1.5-6 packages.
