n Notes on Use
1. When a resistor is connected between the VIN pin and
the input with CMOS output configurations, oscillation
(2) Oscillation as a result of through current
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 (RIN) during release voltage op-
erations. ( refer to diagram 2 )
may occur as a result of voltage drops at R if load cur-
rent (IOUT) exists. ( refer to 5 - (1) below )
IN
2. When a resistor is connected between the VIN pin 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 (IOUT) 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 VIN pin and the
input, detect and release voltage will rise as a result of
the IC’ s supply current flowing through the VIN pin.
Input
AME8550
4. In order to stabilise the IC’ s operations, please en-
sure that VIN pin’ s input frequency’ s rise and fall times
are more than several m sec / V.

(1) Output current oscillation with the CMOS output

Diagram1
When the voltage applied at IN rises, release op-
erations commence and the detector’ s output volt-
age increases. Load current (IOUT) will flow at R.
L
Because a voltage drop ( R x IOUT) is produced at
IN
Input
the R resistor, located between the input (IN) and
IN
the VIN pin, the load current will flow via the IC’ s
VIN pin. The voltage drop will also lead to a fall in

detect operations will commence. Following detect
operations, load current flow will cease and since

begin over again.

Oscillation may occur with this “ release - detect

Further, this condition will also appear via means
of a similar mechanism during detect operations.
