FEATURES
General Description
The MIC809 and MIC810 are inexpensive microprocessor supervisory circuits that monitor 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. Several different reset threshold levels are available to accommodate 3V, 3.3V or 5V powered systems.
• Precision voltage monitor for 3V, 3.3V or 5V power supplies
• /RESET remains valid with VCC as low as 1.4V for SOT- 23 packaged part
• /RESET remains valid with VCC as low as 1V for SC70 packaged part
• Typically less than15µA supply current for SOT-23 packaged part
• 5µ typical supply current for SC70 packaged part
• 140ms minimum reset pulse widths available
• Available in 3-pin SOT-23 and SC-70 package
Applications
• Portable equipment
• Intelligent instruments
• Critical microprocessor power monitoring
• Printers/computers
• Controllers
