CXDR75120 CXDR75121 are microprocessor (μP) supervisory circuits used to monitor the power supplies 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 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. The CXDR75121L has an open-drain output stage, while the CXDR75120 have push-pull outputs. The GCXDR75121’s open-drain RESET output requires a pull-up resistor that can be connected to a voltage higher than VCC. The GCXDR75120 has an active-low RESET output, while the GCXDR75120 has an active-high RESET output. The outputs are guaranteed to be in the correct logic state for VCC down to 0.8V. The CXDR75120/CXDR75121 are available in 5-pin TSOT-23-5 package.
