UIC809 circuits equivalent, microprocessor reset circuits.
* Voltage monitor for 3V or 3.3V or 5V power supplies
* Valid RESET remains with VCC as low as 1V * Typical supply current: 5µA * Fixed 140ms minimum reset pulse width *.
The UTC UIC809 series are resetting circuits which can monitor power supplies especially in microprocessor based systems.
In normal operation, the UTC UIC809 series can assert a reset under any of the following situation: the power supply drops belo.
