n General Description(AME8500BEFTBA22 datasheet and pdf download)
The AME8500 family allows the user to customize the CPU reset function
without any external components. The user has a large choice of reset
voltage thresholds,reset time intervals, and output driver
configurations, all of which are preset at the factory. Each wafer
is trimmed to the customer's specifications.These circuits monitor the
power supply voltage of =ECP based systems. When the power supply
voltage drops below the voltage threshold a reset is asserted
immediately (within an interval T ). The reset remains asserted D1
after the supply voltage rises above the voltage threshold for a time
interval, T . The reset output may be either D2 active high (RESET)
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 for supply voltages greater than 1V.The AME8501 includes
all the above functionality plus an overtemperature shutdown
function. When the ambient temperature exceeds 80 C a reset is
asserted and remains asserted until the temperature falls below 60
C.Space saving SOT23 packages and micropower quiescent current
(<3.0=ECA) make this family a natural for ****table battery powered
equipment.
