 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 V_CC
rises above the designed threshold level.
 FEATURES
* Voltage monitor for 3V or 3.3V or 5V power supplies
* Valid RESET remains with V_CC as low as 1V
* Typical supply current: 5µA
* Fixed 140ms minimum reset pulse width
* With Manual reset input
