MICROPROCESSOR RESET
CIRCUITS
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
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.
FEATURES
* Voltage monitor for 3V or 3.3V power supplies
* Valid RESET remains with VCC as low as 1V
* Typical supply current: 5µA
* Fixed140ms minimum reset pulse width
* With Manual reset input
* Halogen Free

DESCRIPTION
Ground
This pin will fall low after the VCC’s falling below the reset threshold voltage and it also
can remain asserted for at least 140ms min after VCC’s rising upon the reset threshold.
Input of manual reset. A reset can be forced by a logic low on MR . As the MR is held
low, the reset will remain asserted, and until the MR rise high, the reset will
remain140ms min at least. When it is float that means it is unused.
Input of power supply.
