AME8510 Datasheet | Analog Microelectronics

Description The AME8510/8520/8530 family allows the user to customize the CPU monitoring function without any external ponents. 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 VIN. The state of the reset output is guaranteed to be correct down to 1V. After VIN 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 VIN 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”inter...
