GENERAL DESCRIPTION
The MIC809 and 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 accommodate 3V, 3.3V or 5V powered systems. The MIC809 has an active-low /RESET output, while the MIC810 offers an active-high RESET output. Having a push-pull output stage, the MIC809/810 does not require a pull-up resistor at the output. The MIC809 is also available with a shorter reset timeout (30ms, minimum).
