MAX6346
DESCRIPTION
The MAX6326/MAX6327//MAX6328/MAX6346/MAX6347/MAX6348 microprocessor (µP) reset circuits monitor power supplies in µP and digital systems. These devices eliminate external ponents 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 m V 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...
