Semtron ST809
The ST809 series are power supply supervisory circuits used to monitor the supply change in microprocessors and digital systems. The ST809 series provide a reset to the microprocessors during system power-up, power-down and brown-out conditions. The ST809 is designed to monitor the VCC supply voltage and assert a reset signal whenever the voltage declined below the preset threshold.| Part No. | ST809 |

DESCRIPTION
The reset signal remains for at least 140ms after VCC has risen above the threshold. The ST809 provides an active-low reset output. The ST809 series are optimized to reject fast transient glitches on the VCC line. Low power supply current of 10μA makes the ST809 more suitable for battery-powered applications. The ST809 series are available in SOT23-3 package.
