Part Details:

19-1839; Rev 4; 4/07 SC70/µDFN, Single/Dual Low-Voltage, Low-Power µP Reset Circuits MAX6381­MAX6390 General Description Features The MAX6381­MAX6390 microprocessor (µP) supervisory Factory-Set Reset Threshold Voltages Ranging circuits monitor power-supply voltages from +1.8V to from +1.58V to +4.63V in Approximately 100mV +5.0V while consuming only 3µA of supply current at Increments +1.8V. Whenever VCC falls below the factory-set reset ±2.5% Reset Threshold Accuracy Over thresholds, the reset output asserts and remains assert- Temperature (-40°C to +125°C) ed for a minimum reset timeout period after VCC risesabove the reset threshold. Reset thresholds are available Seven Reset Timeout Periods Available: 1ms, from +1.58V to +4.63V, in approximately 100mV incre- 20ms, 140ms, 280ms, 560ms, 1120ms, ments. Seven minimum reset timeout delays ranging 1200ms (min) from 1ms to 1200ms are available. 3 Reset Output Options The MAX6381/MAX6384/MAX6387 have a push-pull Active-Low Push-Pull active-low reset output. The MAX6382/MAX6385/ Active-High Push-Pull MAX6388 have a push-pull active-high reset output, Active-Low Open-Drain and the MAX6383/MAX6386/MAX6389/MAX6390 Reset Output State Guaranteed Valid have an open-drain active-low reset output. The Down to VCC = 1V MAX6384/MAX6385/MAX6386 also feature a Manual Reset Input (MAX6384/MAX6385/MAX6386) debounced manual reset input (with internal pullupresistor). The MAX6387/MAX6388/MAX6389 have an Auxiliary RESET IN auxiliary input for monitoring a second voltage. The (MAX6387/MAX6388/MAX6389) MAX6390 offers a manual reset input with a longer VCC VCC Reset Timeout (1120ms or 1200ms)/Manual reset timeout period (1120ms or 1200ms) and a shorter Reset Timeout (140ms or 150ms) (MAX6390) manual reset timeout (140ms or 150ms). Negative-Going VCC Transient Immunity The MAX6381/MAX6382/MAX6383 are available in Low Power Consumption of 6µA at +3.6V 3-pin SC70 and 6-pin µDFN packages and the and 3µA at +1.8V MAX6384­MAX6390 are available in 4-pin SC70 and 6-pin µDFN packages. Pin Compatible with MAX809/MAX810/MAX803/MAX6326/MAX6327/ Applications MAX6328/MAX6346/MAX6347/MAX6348, and MAX6711/MAX6712/MAX6713
