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.

RESET/

RESETB

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 T_D1). The reset remains asserted

after the supply voltage rises above the voltage threshold

for a time interval, T . 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 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 V _{I N}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 (T_D2).

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 V_INand GND. So the MRB pin should never be driven

higher than V_INor lower than GND.

A reset will be asserted if any of two things happen:

1) V_INdrops below the threshold (V_TH)

2) The MRB pin is pulled low.

Glitch Rejection

The AME8570 family will reject negative going transients

on the V_INline 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) V_INrises above the threshold (V_TH)

2) MRB goes high

Accurate Output State at Low V_IN

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 V_INis 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

V_INis lower than the threshold voltage of the part.
