The MAX6381–MAX6390 microprocessor (µP) supervisory circuits monitor power supply voltages from +1.8V to +5.0V while consuming only 3µA of supply current at +1.8V. Whenever VCC falls below the factory-set reset thresholds, the reset output asserts and remains asserted for a minimum reset timeout period after VCC rises above the reset threshold. Reset thresho.
o Factory-Set Reset Threshold Voltages Ranging from +1.58V to +4.63V in Approximately 100mV Increments o ±2.5% Reset Threshold Accuracy Over Temperature (-40°C to +125°C) o Seven Reset Timeout Periods Available: 1ms, 20ms, 140ms, 280ms, 560ms, 1120ms, 1200ms (min) o 3 Reset Output Options Active-Low Push-Pull Active-High Push-Pull Active-Low Open-Drain o Reset Output State Guaranteed Valid Down to VCC = 1V o Manual Reset Input (MAX6384/MAX6385/MAX6386) o Auxiliary RESET IN (MAX6387/MAX6388/MAX6389) o VCC Reset Timeout (1120ms or 1200ms)/Manual Reset Timeout (140ms or 150ms) (MAX6390) o Negativ.
