MIC811/812

Microprocessor Reset Circuits

General Description

Features

The MIC811 and MIC812 are inexpensive microprocessor

supervisory circuits that monitor power supplies in

microprocessor based systems.

• Precision voltage monitor for 3V, 3.3V or 5V power

supplies

• /RESET remains valid with VCC as low as 1V

• 5μA typical supply current

• 140ms minimum reset pulse width available

• Manual reset input

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.

• Available in 4-pin SOT-143 package

Applications

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 VCC has risen above the designed reset

threshold level. Having a push-pull output stage, the

MIC811/812 does not require a pull-up resistor at the

output. The MIC811/812 comes in a 4-pin SOT-143

package.

• Portable equipment

• Intelligent instruments

• Critical microprocessor power monitoring

• Printers/computers

• Controllers

If a microprocessor voltage supervisor with an open-drain

output stage is needed, see MIC6315.
