1 / 11 page 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 assert- ed 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 incre- ments. Seven minimum reset timeout delays ranging from 1ms to 1200ms are available. The MAX6381/MAX6384/MAX6387 have a push-pull active-low reset output. The MAX6382/MAX6385/ MAX6388 have a push-pull active-high reset output, and the MAX6383/MAX6386/MAX6389/MAX6390 have an open-drain active-low reset output. The MAX6384/MAX6385/MAX6386 also feature a debounced manual reset input (with internal pullup resistor). The MAX6387/MAX6388/MAX6389 have an auxiliary input for monitoring a second voltage. The MAX6390 offers a manual reset input with a longer VCC reset timeout period (1120ms or 1200ms) and a shorter manual reset timeout (140ms or 150ms). The MAX6381/MAX6382/MAX6383 are available in 3-pin SC70 packages and the MAX6384–MAX6390 are avail- able in 4-pin SC70 packages. ________________________Applications Computers Controllers Intelligent Instruments Critical µP and µC Power Monitoring Portable/Battery-Powered Equipment Dual Voltage Systems Features 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 Negative-Going VCC Transient Immunity o Low Power Consumption of 6µA at +3.6V and 3µA at +1.8V o Pin Compatible with MAX809/MAX810/MAX803/MAX6326/MAX6327/ MAX6328/MAX6346/MAX6347/MAX6348, and MAX6711/MAX6712/MAX6713 o Tiny 3-Pin SC70 and 4-Pin SC70 Packages SC70, Single/Dual Low-Voltage, Low-Power µP Reset Circuits ________________________________________________________________ Maxim Integrated Products 1 RESET (RESET) 1 3 VCC GND MAX6381 MAX6382 MAX6383 TOP VIEW 2 SC70 ( ) IS FOR MAX6382 PART TEMP.
