Micrel MIC1810
The MIC1810 is an inexpensive microprocessor supervisory circuit that monitors 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. The MIC1810 has an active low /RESET output.- Min Voltage : 1V
- Max Voltage : 5.5V
- Channels : 1
- Max Operating Temp : 85°C
- Min Operating Temp : -40°C

GENERAL DESCRIPTION
Several different reset threshold levels are available to accommodate 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 VCChas risen above the designated reset threshold level. The MIC1810 comes in a 3-pin SOT-23 package.FEATURES
● Precision voltage monitor for 5%, 10%, or 15% drop in 5V power supplies● /RESET remains valid with VCC as low as 1V
