The CXDR75126/CXDR75127 microprocessor (μP) supervisory circuits monitor system voltages in μP and digital systems. They provide excellent circuit reliability at low cost by eliminating external components. Since the sense pin is separated from power supply, it allows the IC to monitor added power supply. Using the IC with the sense pin separated from power supply enables output to maintain the state of detection even when voltage of the monitored power supply drops to 0V. The VSEN pin of G68_ _09T_ is high impedance and can be used for application of reset threshold programming. Moreover, with the built-in delay circuit, connecting the delay capacitance pin to the capacitor enables the IC to provide an arbitrary release delay time. All of these devices are offered in SOT-23-5, SC-70-5, DFN1.6X1.6-6 and ADNF1.5X1.5-6 packages.
