Analog Microelectronics AME8504
The AME8504 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.| Part No. | AME8504 |

GENERAL DESCRIPTION
When the power supply voltage drops below the voltage threshold a reset is asserted immediately (within an interval TD1). The reset remains asserted after the supply voltage rises above the voltage threshold for a time interval, TD2. The reset output may be either active high (RESET) or active low (RESETB). The reset output may be configured as either push-pull. The state of the reset output is guaranteed to be correct only when supply voltage is greater than 1V. The AME8504 also provide a reset manually by pulling the MRB input to ground. Space saving SC-70 package and micropower quiescent current (<3.0µA) make this family a natural for portable battery powered equipment. n Application l Portable Electronics l Power Supplies l Computer Peripherals l Data Acquisition Systems l Applicatiions using CPUs l Consumer Electronics n Typical Application VIN PUSH BUTTON RESET / RESETB SWITCH MRB GND VIN µP RESET INPUT GND n Functional Block Diagram nFEATURES
