MAX706TCSA Datasheet

PMIC - Supervisors


The MAX706P/R/S/T, MAX706AP/AR/AS/AT, andMAX708R/S/T , MAX706TCSA microprocessor (μP) supervisory circuitsreduce the complexity and number of componentsrequired to monitor +3V power-supply levels in +3V to+5V μP systems. These devices significantly improvesystem reliability and accuracy compared to separateICs or discrete components.The MAX706P/R/S/T and MAX706AP/AR/AS/AT supervisorycircuits provide the following four functions:1) A reset output during power-up, power-down, andbrownout conditions.2) An independent watchdog output that goes low if thewatchdog input has not been toggled within 1.6s.3) A 1.25V threshold detector for power-fail warning,low-battery detection, or for monitoring a powersupply other than the main supply.4) An active-low, manual-reset input.The only difference between the MAX706R/AR,MAX706S/AS, and MAX706T/AT is the reset-thresholdvoltage levels, which are 2.63V, 2.93V, and 3.08V,respectively. All have active-low reset output signals.The MAX706P/AP are identical to the MAX706R/AR,except the reset output signal is active-high. The watchdogtimer function for the MAX706AP/AR/AS/AT disableswhen the WDI input is left open or connected to ahigh-impedance state of a low-leakage tri-state output.The MAX708R/S/T provide the same functions as theMAX706R/S/T and MAX706AR/AS/AT except they donot have a watchdog timer. Instead, they provide bothRESET and RESET outputs. As with the MAX706,devices with R, S, and T suffixes have reset thresholdsof 2.63V, 2.93V, and 3.08V, respectively.These devices are available in 8-pin SO, DIP, andμMAX® packages and are fully specified over the operatingtemperature range.
