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.
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.
