Microprocessor Reset Circuit
Final Information
Micrel
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
