AME8500 / 8501
n General Description
n Typical Operating Circuit
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 µP
based systems. 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 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 80oC a reset is asserted and
remains asserted until the temperature falls below 60oC.
Space saving SOT23 packages and micropower quiescent current (<3.0µA) make this family a natural for
portable battery powered equipment.

RESETB/RESET
This pin can be ordered as RESET or RESETB. RESET is active high.
RESETB is active low. It is also available with an open drain or pushpull
output.
VDD
Positive power supply. A reset is asserted after this voltage drops below
a predetermined level. After V DD rises above that level the reset output
remains asserted until the end of the reset timeout period.

Supply Transients
These devices have a certain immunity to fast negative
going transients. In the following pages the graph titled
“Glitch Rejection” indicates the maximum allowable glitch
amplitude and duration to avoid triggering an unintended
reset. As shown in the graph shorter transients can have
larger amplitudes without triggering resets.
