AME AME8510AEEVAFE29Z

The AME8510/8520/8530 family allows the user to customize the CPU monitoring function without any external components. The user has a large choice of reset voltage thresholds and output driver configurations, all of which are preset at the factory. Each wafer is trimmed to the customer's specifications. These circuits will ignore fast negative going transients on V_IN. The state of the reset output is guaranteed to be correct down to 1V. After V_IN crosses above a factory preset threshold, the AME8510/8520/8530 assert a reset signal. After a predetermined time (the “reset” interval) the reset is deasserted. If V_IN ever drops below the threshold voltage a reset is asserted immediately. In addition to a supply monitoring function the AME8510/8520 also monitor transitions at the watch dog input (WDI). If a logic transition does not occur at the WDI pin within a certain time interval (the “watchdog” interval) then a reset is asserted. The reset deasserts after the reset interval, as explained earlier. The AME8510/8530 can both assert a reset manually by pulling the MRB input to ground. Space saving SOT - 25 packages and micropower quiescent current make this family a natural for portable battery powered equipment. The AME8510/8520/8530 are designed to interface with the reset input of a microprocessor and to prevent CPU execution errors due to power up, power down, and other power supply errors. The AME8510/8520 also monitor the CPU health by checking for signal transitions from the CPU at the WDI input.
