MIC803
3-Pin Microprocessor Supervisor Circuit
with Open-Drain Reset Output General Description Features 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. The MIC803 consumes only 4.5ВµA of supply current and
offers three reset delay periods of 20ms, 140ms, and
1120ms (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.
