AME8550

n General Description

n Functional Block Diagram

TheAME8550 series are highly precise, low power con-

sumption voltage detectors, manufactured using CMOS

and fuse trimming technologies. Detect voltage is ex-

tremely accurate with minimal temperature drift.

(1) CMOS Output without Delay

(CMOS output without delay)

(CMOS output with delay)

1. When input voltage (V_IN) rises above detect voltage

(V_DF), output voltage (V_OUT) will be equal to V_IN.

(V_DF), output voltage (V_OUT) will be equal to V_IN.

( A condition of high impedance exists with Nch open

drain output configurations. )

( A condition of high impedance exists with Nch open

drain output configurations. )

2. When input voltage (V_IN) falls below detect voltage (V_DF),

output voltage (V_OUT) will be equal to the ground voltage

(GND) level.

2. When input voltage (V_IN) falls below detect voltage (V_DF),

output voltage (V_OUT) will be equal to the ground voltage

(GND) level.

3. When input voltage (V_IN) falls to a level below that of

the minimum operating voltage (V_MIN), output will become

unstable. In this condition, V_INwill equal the pulled-up

output ( should output be pulled-up.)

3. When input voltage (V_IN) falls to a level below that of

the minimum operating voltage (V_MIN), output will become

unstable. In this condition, V_INwill equal the pulled-up

output ( should output be pulled-up.)

4. When input voltage (V_IN) rises above the ground volt-

age (GND) level, output will be unstable at levels below

the minimum operating voltage (V_MIN). Between the V_MIN

and detect release voltage (V_DR) levels, theground voltage

(GND) level will be maintained.

4. When input voltage (V_IN) rises above the ground volt-

age (GND) level, output will be unstable at levels below

the minimum operating voltage (V_MIN). Between the V_MIN

and detect release voltage (V_DR) levels, theground volt-

age (GND) level will be maintained.

5. When input voltage (V_IN) rises above detect release

voltage (V_DR), output voltage (V_OUT) will be equal to V_IN.

n Notes on Use

(2) Oscillation as a result of through current

1. When a resistor is connected between the V_INpin and

the input with CMOS output configurations, oscillation

may occur as a result of voltage drops at R_INif load cur-

rent (I_OUT) exists. ( refer to 5 - (1) below )

Since the AME8550 series are CMOS IC’ S,

through current will flow when the IC’ s internal cir-

cuit switching operates(during release and detect

operations ).Consequently, oscillation is liable to

occur as a result of drops in voltage at the through

current’ s resistor (R_IN) during release voltage op-

erations. ( refer to diagram 2 )

2. When a resistor is connected between the V_INpin and

the input with CMOS output configurations, irrespective

of Nch output configurations, oscillation may occur as a

result of through current at the time of voltage release

even if load current (I_OUT) does not exist.( refer to 5 - (1)(2)

below )

Since hysteresis exists during detect operations,

oscillation is unlikely to occur.

3. With a resistor connected between the V_INpin and the

input, detect and release voltage will rise as a result of

the IC’ s supply current flowing through the V_INpin.

Input

AME8550

4. In order to stabilise the IC’ s operations, please en-

sure that V_INpin’ s input frequency’ s rise and fall times

are more than several m sec / V.

5. Oscillation

GND

(1) Output current oscillation with the CMOS output

configuration

Diagram1

When the voltage applied at IN rises, release op-

erations commence and the detector’ s output volt-

age increases. Load current (I_OUT) will flow at R_L.

Because a voltage drop ( R_INx I_OUT) is produced at

the R_INresistor, located between the input (IN) and

the V_INpin, the load current will flow via the IC’ s

V_INpin. The voltage drop will also lead to a fall in

the voltage level at the V_INpin. When the V_INpin

voltage level falls below the detect voltage level,

detect operations will commence. Following detect

operations, load current flow will cease and since

voltage drop at R_INwill disappear, the voltage level

at the V_INpin will rise and release operations will

begin over again.
