MIC811/812  
Microprocessor Reset Circuits  
General Description  
Features  
The MIC811 and MIC812 are inexpensive microprocessor  
supervisory circuits that monitor power supplies in  
microprocessor based systems.  
Precision voltage monitor for 3V, 3.3V or 5V power  
supplies  
/RESET remains valid with VCC as low as 1V  
5μA typical supply current  
140ms minimum reset pulse width available  
Manual reset input  
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.  
Available in 4-pin SOT-143 package  
Applications  
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.  
Portable equipment  
Intelligent instruments  
Critical microprocessor power monitoring  
Printers/computers  
Controllers  
If a microprocessor voltage supervisor with an open-drain  
output stage is needed, see MIC6315.
