AME8500 / 8501
µProcessor Supervisory
n General Description
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.
n Typical Operating Circuit

Processor
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 (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 or open
drain. The state of the reset output is guaranteed to be
correct for supply voltages greater than 1V.

Note: * External pull-up resistor is required if open-
drain output is used. 10 kΩ is recommended.
The AME8501 includes all the above functionality plus
an overtemperature shutdown function. When the ambi-
ent temperature exceeds 80oC a reset is asserted and
remains asserted until the temperature falls below 60oC.
Space saving SOT23 packages and micropower qui-
escent current (<3.0µA) make this family a natural for
portable battery powered equipment.
