General Description
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 to accommodate 5%, 10%, or 15% drop in 5V powered systems.
The MIC1810 has an active low /RESET output. The reset output is guaranteed to remain asserted for a minimum of 100ms after V
CChas risen above the designated reset threshold level. The MIC1810 comes in a 3-pin SOT-23 package.

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
