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  
D2  
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.

The AME8570 also provide a reset manually by pulling

Space saving SC-70 package and micropower quies-

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.
