MAX6326-31D

The MAX6326-31D | MAX6326UR31-T | MAX6326-22D | MAX6326-22W |MAX6326-23W | MAX6326-26W belongs to the MAX6326 series.The MAX6326-31D/MAX6327//MAX6328/MAX6346/MAX6347/MAX6348 microprocessor (mP) reset circuits monitor power supplies in mP and digital systems. The MAX6326-31D eliminate external components and adjustments while providing excellent circuit reliability and low cost solution. They are used to monitor 2.5 V, 3 V, 3.3 V and 5 V power supplies.They assert a reset signal when the VDD supply voltage falls below a preset reset threshold voltage. The reset signal remains asserted for at least 100 ms after the VDD rises above the reset threshold. The reset threshold are factory trimmable from 2.2 V to 4.63 V in approximately 100 mV increments. All these parts are guaranteed to assert a reset for VDD down to 1 V. They have excellent immunity to fast transients on VDD.The devices vary in their output configuration. The MAX6326/MAX6346 have push-pull, active-LOW reset output; while the MAX6328/MAX6348 have open drain, active-LOW reset output.The MAX6327/MAX6347 have push-pull, active HIGH reset output.The lower threshold MAX6326-31D/MAX6327/MAX6328 have ultra-low supply current of typically 0.5 mA making them ideal for battery powered applications. All six devices are available in both the 3-pin SOT23 and SC70 packages.
