MIC811/812  
Microprocessor Reset Circuits  
Final Information  
General Description  
Features  
The MIC811 and MIC812 are inexpensive microprocessor  
supervisory circuit that monitors power supplies in micropro-  
cessor based systems.  
• Precision voltage monitor for 3V, 3.3V or 5V power  
supplies  
• /RESET remains valid with V as low as 1.4V  
CC  
• <15µA supply current  
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.  
• 140ms minimum reset pulse width available  
• Manual reset input  
• Available in 4-pin SOT-143 package  
Applications  
The MIC811 has an active low /RESET output, while the  
MIC812offersanactivehighRESEToutput.Theresetoutput  
is guaranteed to remain asserted for a minimum of 140ms  
• Portable equipment  
• Intelligent instruments  
• Critical microprocessor power monitoring  
• Printers/computers  
after V has risen above the designed reset threshold level.  
CC  
Having a push-pull output stage, MIC811/812 does not  
require a pull-up resistor at the output. The MIC811/812  
comes in a 4-pin SOT-143 package.  
• Embedded controllers  
If a microprocessor voltage supervisor with an open-drain  
output stage is needed, see MIC6315.
