The AME8510/8520/8530 family allows the ur to cus-tomize the CPU monitoring function without any external components. The ur has a large choice of ret volt-age thresholds and output driver confi
gurations, all of which are pret at the factory. Each wafer is trimmed to the customer's specifications.
The circuits will ignore fast negative going transients on V DD . The state of the ret output is guaranteed to be correct down to 1V.
After V DD cross above a factory pret threshold,the AME8510/8520/8530 asrt a ret signal. After a predetermined time (the “ret” interval) the ret is deasrted. If V DD ever drops below the threshold voltage a ret is asrted immediately. In addition to a supply monitoring function the AME8510/8520 also monitor tran-sitions at the watch dog (WDI) input. If a logic transition does not occur at the WDI pin within a certain time inter-val (the “watchdog” interval) then a ret is asrted. The ret deasrts after the ret interval, as explained ear-lier.
The AME8510/8530 can both asrt a ret manually by pulling the MRB input to ground.
Space saving SOT-25 packages and micropower qui-escent current make this family a natural for portable battery powered equipment.
