Overview
ft809 3-Pin Microprocessor Reset Circuits GENERAL DESCRIPTION The ft809 series are power supply supervisory circuits used to monitor the power supplies in microprocessors and digital systems.
The ft809 series provide a reset to the microprocessors during system power-up, power-down and brown-out conditions.
The ft809 is designed to monitor the VCC supply voltage and asserts a reset signal whenever the supply voltage declines below the preset threshold.
The reset signal remains asserted for at least 140ms after VCC has risen above the threshold.
The ft809 provides an active-low reset output.
The ft809 series are optimized to reject fast transients on the VCC.
Low supply current of 10µA makes...
