AME8570 Push-Pull RESET/ RESETB
The AME8570 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 mP
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, T . The reset output may be either

AME8570 Open-Drain RESETB
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 only when supply voltage is greater than
1V.

Space saving SC-70 package and micropower quies-
cent current ( < 3.0mA ) make this family a natural for
portable battery powered equipment.

Ground
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 push-pull output.
RESET/RESETB
Positive power supply. A reset is asserted after this voltage drops below a predetermined
level. After VIN 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.

n Detailed Description
The AME8570 are designed to interface with the reset
input of a microprocessor and to prevent code-execution
errors due to power up, power down, and other power
supply errors.
Manual Reset Input
The AME8570 feature a manual reset feature (MRB).
A logic low on the MRB pin asserts a reset. The reset
remains asserted as long as the MRB pin remains low.
After the MRB pin transitions to a high state the reset
remains asserted for the prescribed reset interval (TD2).
Reset Output
The MRB pin is internally pulled up to V by a 100K
resistor. It is internally debounced to reject switching
transients.
Each output pin in the family can be configured to be
either push-pull or open-drain. In addition each output may
be either active high or active low. Active high reset out-
puts are denoted as RESET. Active low reset outputs
are denoted as RESETB. The selection guide on this
data sheet shows all possible combinations of output
driver configuration.
IN
The MRB pin is ESD protected by diodes connected
to VIN and GND. So the MRB pin should never be driven
higher than VIN or lower than GND.
A reset will be asserted if any of two things happen:
Glitch Rejection
1) VIN drops below the threshold (VTH
2) The MRB pin is pulled low.
)
The AME8570 family will reject negative going transients
on the VIN line to some extent. The smaller the duration
of the transient the larger its amplitude may be without
triggering a reset. The "Glitch Rejection" chart in the
graphs section of this datasheet shows the relation be-
tween glitch amplitude and allowable glitch duration to
avoid unintended resets.
The reset will remain asserted for the prescribed reset
interval after:
1) VIN rises above the threshold (VTH
2) MRB goes high
)
Accurate Output State at Low VIN
With V voltage on the order of the MOS transistor
IN
threshold (<1.0V) the outputs of the AME8570 may be-
come undefined. For parts with active low output
(RESETB) a resistor placed between RESETB and GND
on the order of 100K will ensure that the RESETB output
stays low when VIN is lower than the threshold voltage of
the part. In a like manner a resistor on the order of 100K
when placed between RESET and V will ensure parts
IN
with active high output (RESET) will remain high when
VIN is lower than the threshold voltage of the part.
