The MIC809 and MIC810 are inexpensive microprocessor supervisory circuit that monitors power supplies in microprocessor based systems. The function of this device is to assert a reset if either 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
• <15µA supply current
• 20ms, 40ms, or 1100ms minimum reset pulse widths available
• Manual reset input
• Available in 3-pin SOT-23 package
Applications
•
•
•
•
• Portable equipment Intelligent instruments Critical microprocessor power monitoring Printers/computers Controllers
