MIC809/810  
Microprocessor Reset Circuits  
General Description  
The MIC809 and MIC810 are inexpensive microprocessor  
supervisory circuits that monitor power supplies in micro-  
processor based systems.  
• Precision voltage monitor for 3V, 3.3V or 5V power sup-  
plies  
• /RESET remains valid with V as low as 1.4V for SOT-  
CC  
23 packaged part  
• /RESET remains valid with VCC as low as 1V for SC70  
packaged part  
• Typically less than15µA supply current for SOT-23 pack-  
aged part  
• 5µ typical supply current for SC70 packaged part  
• 140ms minimum reset pulse widths available  
• Available in 3-pin SOT-23 and SC-70 package  
The function of these devices is to assert a reset if the power  
supplydropsbelowadesignatedresetthresholdlevel.Several  
differentresetthresholdlevelsareavailabletoaccommodate  
3V, 3.3V or 5V powered systems.  
The MIC809 has an active-low /RESET output, while the  
MIC810offersanactive-highRESEToutput.Theresetoutput  
is guaranteed to remain asserted for a minimum of 140ms  
after V  
has risen above the designated reset threshold  
CC  
level. Having a push-pull output stage, the MIC809/810 does  
not require a pull-up resistor at the output. The MIC809/810  
comes in a 3-pin SOT-23 and SC-70 package.  
Applications  
• Portable equipment  
• Intelligent instruments  
• Critical microprocessor power monitoring  
• Printers/computers  
The MIC809 is also available with a shorter reset timeout  
(30ms min.). See the MIC809-5.
