MIC803 3-Pin Microprocessor Supervisor Circuit with Open-Drain Reset Output General Description Features The MIC803 is a single-voltage supervisor with open-drain 4.5A supply current (typical) at 3.6V reset output that provides accurate power supply Open-drain /RESET output monitoring and reset generation in microprocessor-based /RESET remains valid with V as low as 1V CC systems. The function of the device is to assert a reset 20ms, 140ms, or 1120ms (minimum) reset timeout signal if the power supply voltage drops below the reset options threshold voltage, and retain this reset for the reset timeout period once the power supply increases above the 2.63V to 4.63V preset voltage threshold options reset threshold voltage. 2.5% voltage threshold accuracy over temperature 3-pin SC70-3 package (2.0mm 2.1mm) The MIC803 consumes only 4.5A of supply current and offers three reset delay periods of 20ms, 140ms, and 3-pin SOT-23 package (2.3mm 2.9mm) 1120ms (minimum). It features factory-programmed reset -40C to +125C junction temperature range threshold levels from 2.63V to 4.63V to accommodate 3.0V, 3.3V, and 5.0V power supplies. It is available in the Applications compact 3-pin SC-70 and SOT-23 packages.
