CONSONANCE Ultra Low Power Microprocessor Reset IC CN803/809/CN810 General Description The CN803/809/810 series are micro- processor (µP) supervisory circuits used to monitor the power supplies in µP and digital systems. They provide excellent circuit reliability and low cost by eliminating external components. These circuits perform a single function: they assert a reset signal whenever the VCC supply voltage declines below a preset threshold, keeping it asserted for at least 140ms after VCC has risen above the reset threshold. The CN809/810 have CMOS outputs, the CN803 has open drain output. The CN803/809 have an active-low output, while the CN810 has an active-high RESET output.
