DESCRIPTION
The UTC UIC811 series are resetting circuits which can monitor power supplies especially in microprocessor based systems.
In normal operation, the UTC UIC811 series can assert a reset under any of the following situation: the power supply drops below a designated reset threshold level (which is available for 3V or 3.3V or 5V system) or MR is forced low.
There is an internal active low RESET output which has already been guaranteed to remain asserted for at 140ms least while VCC rises above the designed threshold level.
