AME8570M

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 to be correct only when supply voltage is greater than 1V. The AME8570M 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 Features l Small Packages : SC-70-4, SOT-23, TSOT-23A, SOT-25, TSOT-25A, SOT-143 l Tight Voltage Threshold Tolerance:¡Ó1.50% l Wide Temperature Range : -40OC to +85OC l Low Quiescent Current <3.0µA l Manual Reset Input Option l Green Products Meet RoHS Standards n Applications l Portable Electronics l Power Supplies l Computer Peripherals l Data Acquisition Systems l Applications using CPUs l Consumer Electronics Re...
