Notes on Using PST623

Be sure to give an incline of more than 30μS to rise and fall for input with varied power supply voltage (V
CC
)
and bleeder resistance.
Also, when setting input bleeder resistance, VS pin input current is affected and the detection voltage setting
will differ from the set value if current on the bleeder resistor is too low.
Use input bleeder resistor R2 at 250k
or less.
2. Delay time setting
H transmission delay time can be set easily as follows from the TC pin, using the external capacitor.
T = Cd (2.33 106) [S]
Use the external capacitor at 1μF (approx. 2.33S) or less.
