Description
The MIC1810 is an 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 5%, 10%, or 15% drop in 5V powered systems.
The MIC1810 has an active low RESET output. The reset output is guaranteed to remain asserted for a minimum of 100ms after VCC has risen above the designated reset threshold level. The MIC1810 comes in a 3-pin SOT-23 package.
