MIC803

3-Pin Microprocessor Supervisor Circuit with Open-Drain Reset Output

Features

General Description

• 4.5 µA Supply Current (Typical) at 3.6V

• Open-Drain /RESET Output

The MIC803 is a single-voltage supervisor with

open-drain reset output that provides accurate power

supply monitoring and reset generation in

microprocessor-based systems. The function of the

device is to assert a reset signal if the power supply

voltage drops below the reset threshold voltage, and

retain this reset for the reset timeout period once the

power supply increases above the reset threshold

voltage.

• /RESET Remains Valid with V_CCas Low as 1V

• 20 ms, 140 ms, or 1120 ms Minimum Reset

Timeout Options

• 2.63V to 4.63V Preset Voltage Threshold Options

• 2.5% Voltage Threshold Accuracy over

Temperature

• 3-Pin SC-70 Package (2.0 mm x 2.1 mm)

• 3-Pin SOT-23 Package (2.3 mm x 2.9 mm)

• –40°C to +125°C Junction Temperature Range

The MIC803 consumes only 4.5 μA of supply current

and offers three reset delay periods of 20 ms, 140 ms,

and 1120 ms (minimum).

It features factory-programmed reset threshold levels

from 2.63V to 4.63V to accommodate 3.0V, 3.3V, and

5.0V power supplies. It is available in the compact 3-pin

SC-70 and SOT-23 packages.

Applications

• Critical Microcomputer Power Monitoring

• Portable Equipment

• Solid State Drives

• Printers/Computers

• Embedded Controllers
