CXDR75120 CXDR75121

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.
