Microprocessor Reset Circuits
Final Information
General Description
The MIC811 and MIC812 are inexpensive microprocessor
supervisory circuit that monitors power supplies in micropro-
cessor based systems.
The function of this device is to assert a reset if either the
power supply drops below a designated reset threshold level
or /MR is forced low. Several different reset threshold levels
are available to accommodate 3V, 3.3V or 5V powered
systems.
The MIC811 has an active low /RESET output, while the
MIC812 offers an active high RESET output. The reset output
is guaranteed to remain asserted for a minimum of 140ms
after V
CC
has risen above the designed reset threshold level.
Having a push-pull output stage, MIC811/812 does not
require a pull-up resistor at the output. The MIC811/812
comes in a 4-pin SOT-143 package.
If a microprocessor voltage supervisor with an open-drain
output stage is needed, see MIC6315.
Features
• Precision voltage monitor for 3V, 3.3V or 5V power
supplies
• /RESET remains valid with V
CC
as low as 1.4V
• <15µA supply current
• 140ms minimum reset pulse width available
• Manual reset input
• Available in 4-pin SOT-143 package
Applications
Portable equipment
Intelligent instruments
Critical microprocessor power monitoring
Printers/computers
Embedded controllers
