MIC809/MIC810

Microprocessor Reset Circuits

Features

General Description

• Precision Voltage Monitor for 3V, 3.3V, or 5V

Power Supplies

The MIC809 and MIC810 are inexpensive

microprocessor supervisory circuits that monitor power

supplies in microprocessor-based systems.

• /RESET Remains Valid with V_CCas Low as 1.4V

for the SOT-23

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 3V, 3.3V, or 5V powered

systems.

• /RESET Remains Valid with V_CCas Low as 1V for

the SC-70

• Typically Less Than 15 µA Supply Current for the

SOT-23

• 5 µA Typical Supply Current for the SC-70

• 140 ms Minimum Reset Pulse Width Available

• Available in 3-Lead SOT-23 and SC-70 Packages

The MIC809 has an active-low /RESET output, while

the MIC810 offers an active-high RESET output. The

reset output is guaranteed to remain asserted for a

minimum of 140 ms after V_CChas risen above the

designated reset threshold level. Having a push-pull

output stage, the MIC809/810 do not require a pull-up

resistor at the output. The MIC809/810 come in a

3-lead SOT-23 and SC-70 package.

Applications

• Portable Equipment

• Intelligent Instruments

• Critical Microprocessor Power Monitoring

• Printers/Computers

The MIC809 is also available with a shorter reset

timeout (30 ms, minimum).

• Controllers
