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 ) 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. 4. In order to stabilise the IC’ s operations, please ensure that VIN 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. Input RIN RIN xIOUT voltage drop AME8550 IOUT VIN 5. Oscillation VOUT GND (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 VIN pin, the load current will flow via the IC’ s VIN pin. The voltage drop will also lead to a fall in the voltage level at the VIN pin. When the VIN 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 VIN pin will rise and release operations will begin over again. Oscillation may occur with this “ release - detect - release” repetition.
