ft809 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.
