1. Switching OFF time and noise cancellation time calculations
Notes on the CR pin setting (switching off time and noise canceller time)
The noise canceller time (Tn) and the switching off time (Toff) are set using the following formulas.
When VCC=5V
Noise canceller time (Tn)
Tn
≈ C R ln {(1.5 - RI)/(4.0 - RI)} [s]
CR pin charge current: 1.25mA
Switching off time (Toff)
Toff
≈ -C R ln (1.5/4.8) [s]
Component value ranges
R: 5.6k
to 100k
C: 470pF to 2000pF
When VCC=3.3V
Noise canceller time (Tn)
Tn
≈ C R ln {(1.06 - RI)/(2.66 - RI)} [s]
CR pin charge current: 0.7mA
Switching off time (Toff)
Toff
≈ -C R ln (1.06/3.1) [s]
