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

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

FEATURES

* Voltage monitor for 3V or 3.3V or 5V power supplies

* Typical supply current: 5µA

* Fixed 140ms minimum reset pulse width

* With Manual reset input
