n Notes on Use
1. When a resistor is connected between the VDD pin and
the input with CMOS output configurations, oscillation
may occur as a result of voltage drops at RIN if load current (IOUT) exists. ( refer to 5 - (1) below )
2. When a resistor is connected between the VDD 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 )
3. With a resistor connected between the VDDpin and the
input, detect and release voltage will rise as a result of
the IC’s supply current flowing through the VDD pin.
4. In order to stabilise the IC’s operations, please ensure that VDD pin’s input frequency’s rise and fall times
are more than several µ sec / V.
(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 circuit 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 operations. ( refer to diagram 2 )
Since hysteresis exists during detect operations,
oscillation is unlikely to occur.

5. Oscillation
VSS
(1) Output current oscillation with the CMOS output
configuration
When the voltage applied at IN rises, release operations commence and the detector’s output voltage increases. Load current (IOUT) will flow at RL.
Because a voltage drop ( RIN x IOUT) is produced at
the RIN resistor, located between the input (IN) and
the VDD pin, the load current will flow via the IC’s
VDD pin. The voltage drop will also lead to a fall in
the voltage level at the VDD pin. When the VDD pin
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 RIN will disappear, the voltage level
at the VDD pin will rise and release operations will
begin over again.
Oscillation may occur with this “ release - detect - release “ repetition.
Further, this condition will also appear via means
of a similar mechanism during detect operations.
