Microprocessor Reset Circuit
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
CC
has risen above the designated reset thresh-
old 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 V
CC
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
