Microprocessor Reset Circuit
Final Information
Micrel
General Description
The MIC8115 is an inexpensive microprocessor supervisory
circuit that monitors power supplies 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 MIC8115 has an active low /RESET output. The reset
output is guaranteed to remain asserted for a minimum of
1100ms after VCC has risen above the designated reset
threshold level. The MIC8115 comes in a 4-pin SOT-143
package.
Features
• Precision voltage monitor for 3.3V power supplies
Specifically tailored to theAMD Elan SC500 Series
• /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
