Description
The MIC809/MIC810 are inexpensive microprocessor supervisory circuits that monitor power supplies in microprocessor based systems.
The function of these devices is to assert a reset if the power supply drops below a designated reset threshold level. Several different reset threshold levels are available to accomodate 3V, 3.3V or 5V powered systems.

FEATUREs
◾ RESET Remains Valid with VCC as Low as 1.4V
◾ Precision Voltage Monitor for 3V, 3.3V or 5V Power Supplies
◾ Available in 3-Pin SOT23 Package
◾ <15µA Supply Current
◾ 140ms Minimum Reset Pulse Width
◾ No External Components Required

Typical Applications
◾ Portable Equipment
◾ Intelligent Instruments
◾ Critical Microprocessor Power Monitoring
◾ Printers/Computers
◾ Controllers
