General Description
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 thresholds are available from +1.58V to +4.63V, in approximately 100mV increments. Seven minimum reset timeout delays ranging from 1ms to 1200ms are available.

Features
♦ Factory-Set Reset Threshold Voltages Ranging from +1.58V to +4.63V in Approximately 100mV Increments
♦ ±2.5% Reset Threshold Accuracy Over Temperature (-40°C to +125°C)
♦ Seven Reset Timeout Periods Available: 1ms, 20ms, 140ms, 280ms, 560ms, 1120ms, 1200ms (min)
♦ 3 Reset Output Options
   Active-Low Push-Pull
   Active-High Push-Pull
   Active-Low Open-Drain
♦ Reset Output State Guaranteed Valid Down to VCC = 1V
♦ Manual Reset Input (MAX6384/MAX6385/MAX6386)
♦ Auxiliary RESET IN (MAX6387/MAX6388/MAX6389)
♦ VCC Reset Timeout (1120ms or 1200ms)/Manual
          Reset Timeout (140ms or 150ms) (MAX6390)
♦ Negative-Going VCC Transient Immunity
♦ Low Power Consumption of 6µA at +3.6V and 3µA at +1.8V
♦ Pin Compatible with MAX809/MAX810/MAX803/MAX6326/MAX6327/MAX6328/MAX6346/MAX6347/MAX6348, and MAX6711/MAX6712/MAX6713
♦ Tiny 3-Pin/4-Pin SC70 and 6-Pin µDFN Packages
