AME AME8570M n General Description The AME8570M family allows the user to customize the CPU reset function without any external components. The user has serveral choice of reset voltage thresholds, reset time intervals, and output driver configurations, all of which are preset at the factory. These circuits monitor the power supply voltage of µP based systems. When the power supply voltage drops below the voltage threshold a reset is asserted immedi- ately after ( within an the supply interval voltage TrisD1e)s. The reset above the remains asserted voltage threshold faocrtiavetimhieghin(teRrvEaSl,ETTD2). The reset output may be either or active low ( RESETB ). The reset output may be configured as either push/pull or open drain. The state of the reset output is guaranteed [ ... ]
