Part Details:

19-1756; Rev 3; 12/05 Quad Voltage µP Supervisory Circuit in SOT Package MAX6339 General Description Features The MAX6339 is a precision quad voltage monitor with Monitors Four Power-Supply Voltages microprocessor (µP) supervisory reset timing. The devicecan monitor up to four system supply voltages without Precision Factory-Set Reset Threshold Options any external components and asserts a single reset if any for +5.0V, +3.3V, +3.0, +2.5V, +1.8V, and -5.0V supply voltage drops below its preset threshold. The Supplies device significantly reduces system size and component User-Adjustable Voltage Monitoring Threshold count while improving reliability compared to separate Options ICs or discrete components. A variety of factory-trimmed threshold voltages are avail- Low 55µA Supply Current able to accommodate different supply voltages and toler- Open-Drain RESET Output with 10µA Internal ances with minimal external component requirements. Pullup The selection includes internally fixed options for monitor-ing +5.0V, +3.3V, +3.0V, +2.5V, +1.8V, and -5.0V sup- 140ms (min) Reset Timeout Period plies with -5% and/or -10% tolerances. The device is also RESET Valid to IN1 = 1V or IN2 = 1V available with one or two user-adjustable thresholdoptions if non-standard thresholds are desired (use exter- Immune to Short Monitored Supply Transients nal resistor-divider network). No External Components Required The quad monitor provides a single active-low reset out- put that is asserted when any monitored input is below its Guaranteed from -40°C to +85°C associated threshold. The output is open drain with a Small 6-Pin SOT23 Package weak internal pullup (10µA) to IN2. Reset remains low fora reset timeout period (140ms min) after all voltages areabove the selected thresholds. The output is valid as long Ordering Information as either the IN1 or IN2 input voltage remains > 1V. PART TEMP. RANGE PIN-PACKAGE The MAX6339 is available in a small 6-pin SOT23 pack-age and operates over the extended (-40°C to +85°C) MAX6339_UT-T* -40°C TO +85°C 6 SOT23-6 temperature range. *Insert the desired letter from the Selector Guide into the blank ________________________Applications to complete the part number. There is a 2500 piece minimumorder increment requirement on the SOT package and these Telecommunications devices are available in tape-and-reel only.
