Product Summary

The MIC1810-5UYTR is an inexpensive microprocessor supervisory circuit that monitors power supplies in microprocessor based systems. The function of the MIC1810-5UYTR 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 5%, 10%, or 15% drop in 5V powered systems. The applications of the MIC1810-5UYTR are Portable equipment, Intelligent instruments, Critical microprocessor power monitoring, Printers/computers, Embedded controllers.
