Part Details:

19-1294; Rev 4; 12/05 3-Pin, Ultra-Low-Power SC70/SOT µP Reset Circuits MAX6326/MAX6327/MAX6328/MAX6346/MAX6347/MAX6348 General Description Features The MAX6326/MAX6327/MAX6328/MAX6346/MAX6347/ Ultra-Low 1µA (max) Supply Current MAX6348 microprocessor (µP) supervisory circuits moni- (MAX6326/MAX6327/MAX6328) tor the power supplies in µP and digital systems. These Precision Monitoring of 2.5V, 3V, 3.3V, and 5V devices provide excellent circuit reliability and low cost Power-Supply Voltages by eliminating external components and adjustmentswhen used with 2.5V, 3V, 3.3V, and 5V powered circuits. Reset Thresholds Available from 2.2V to 4.63V These circuits perform a single function: they assert a Fully Specified Over Temperature reset signal whenever the VCC supply voltage declines 100ms (min) Power-On Reset Pulse Width below a preset threshold, keeping it asserted for at least Low Cost 100ms after VCC has risen above the reset threshold.The only difference between the devices is their output. Available in Three Versions: Push-Pull RESET, The MAX6326/MAX6346 (push-pull) and MAX6328/ Push-Pull RESET, and Open-Drain RESET MAX6348 (open-drain) have an active-low reset output. Power-Supply Transient Immunity The MAX6327/MAX6347 have an active-high push-pull No External Components reset output. All of these parts are guaranteed to be inthe correct state for V 3-Pin SC70/SOT23 Packages CC down to 1V. The reset compara- tor is designed to ignore fast transients on VCC. Reset Pin Compatible with MAX803/MAX809/MAX810 thresholds are factory-trimmable between 2.2V and4.63V, in approximately 100mV increments. Twenty-one Ordering Information standard versions are available. Contact the factory foravailability of nonstandard versions. PART TEMP. RANGE PIN-PACKAGE Ultra-low supply currents (1µA max for the MAX6326/ MAX6326XR_ _-T -40°C to +85°C 3 SC70-3 MAX6327/MAX6328) make these parts ideal for use in MAX6326UR_ _-T -40°C to +85°C 3 SOT23-3 portable equipment. All six devices are available in MAX6327XR_ _-T -40°C to +85°C 3 SC70-3 space-saving SOT23 and SC70 packages. MAX6327UR_ _-T
