Microprocessor Reset Circuits
General Description
The MIC811 and MIC812 are inexpensive microprocessor
supervisory circuits that monitor power supplies in
microprocessor based systems.
The function of this device is to assert a reset if either the
power supply drops below a designated reset threshold
level or /MR is forced low. Several different reset threshold
levels are available to accommodate 3V, 3.3V or 5V
powered systems.
The MIC811 has an active low /RESET output, while the
MIC812 offers an active high RESET output. The reset
output is guaranteed to remain asserted for a minimum of
140ms after VCC has risen above the designed reset
threshold level. Having a push-pull output stage, the
MIC811/812 does not require a pull-up resistor at the
output. The MIC811/812 comes in a 4-pin SOT-143
package.
If a microprocessor voltage supervisor with an open-drain
output stage is needed, see MIC6315.
