MIC1810 Microprocessor Reset Circuit

MIC1810 Microprocessor Reset Circuit

The MIC1810 is an inexpensive microprocessor supervisory circuit that monitors 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.

Features

• Precision voltage monitor for 5%, 10%, or 15% drop in 5V power supplies
• /RESET remains valid with VCC as low as 1V
• 5µA supply current (typical)
• 100ms minimum reset pulse width
• No external components required
• Available in 3-pin SOT-23 package Applications
• Portable equipment
• Intelligent instruments
• Critical microprocessor power monitoring
• Printers/computers
• Embedded controllers Ordering Information Part Number MIC1810-5U MIC1810-10U MIC1810-15U MIC1810-5UY MIC1810-10UY MIC1810-15UY Marking* NA NB NC NA NB NC Threshold Voltage 4.62V 4.37V 4.12V 4.62V 4.37V 4.12V * Under.
