CXDR75113 CXDR75114 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 is high impedance and can be used for application of reset threshold programming. Moreover, with the built-in reset timeout delay about 800ms, enables the IC remains asserts after the VSEN has risen above reset threshold or manual reset is deasserted. The CXDR75113/CXDR75114 is available in SOT-23-5 packages.
