Microprocessor Reset Circuit Final Information
General Description
The MIC8114 is an inexpensive microprocessor supervisory circuit that monitors the power supply in microprocessor based systems. The function of this device is to assert a reset if the power supply drops below a designated reset threshold level or /MR is forced low. The MIC8114 has an active low /RESET output. The reset output is guaranteed to remain asserted for a minimum of 790ms after VCC has risen above the designated reset threshold level. The MIC1814 comes in a 4-pin SOT-143 package.
Features
Precision voltage monitor for 3.3V power supplies Specifically tailored to the AMD Elan SC400/410 /RESET remains valid with VCC as low as 1.4V <15µA supply current 1100ms minimum reset pulse width Manual reset input Available in 4-Pin SOT-143 Package
Applications
Portable equipment Intelligent instruments Critical microprocessor power monitoring Printers/computers Embedded controllers
