RUNIC RS809
The RS809 microprocessor (µP) supervisory circuits reduce the complexity and number of components required to monitor power-supply and battery function in µP systems. This device significantly improves system reliability and accuracy compared to separate ICs or discrete 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 200ms after VCC has risen above the reset threshold.| Part No. | RS809 |

The RS809 have an active-low RESET output. The reset comparator is designed to ignore fast transients on VCC, and the outputs are guaranteed to be in the correct logic state for VCC down to 1.0V. Low supply current makes the RS809 ideal for use in portable equipment. The RS809 is available in Green SOT23 package.
