SC70/µDFN, Single/Dual Low-Voltage,

Low-Power µP Reset Circuits

棋牌游戏General Description

Features

棋牌游戏The MAX6381–MAX6390 microprocessor (µP) supervisorycircuits monitor power-supply voltages from +1.8V to Factory-Set Reset Threshold Voltages Rangingfrom +1.58V to +4.63V in Approximately 100mV+5.0V while consuming only 3µA of supply current atIncrements

+1.8V. Whenever VCCfalls below the factory-set resetthresholds, the reset output asserts and remains assert- ±2.5% Reset Threshold Accuracy Overed for a minimum reset timeout period after VTemperature (-40°C to +125°C)above the reset threshold. Reset thresholds are availableCCrises 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 ranging1200ms (min)from 1ms to 1200ms are available.
