Power Supply Current
The Electrical Characteristics table specifies the supply
current while the part is idle (waiting to be triggered).
IS(IDLE) varies with the programmed tOUT and the supply
voltage. Once triggered, the instantaneous supply current
increases to IS(ACTIVE) while the timing circuit is active.
IS(ACTIVE) = IS(IDLE) + IS(ACTIVE)
The average increase in supply current
IS(ACTIVE) de-
pends on the output duty cycle (or negative duty cycle,
if POL = 1), since that represents the percentage of time
that the circuit is active. IS(IDLE) and IS(ACTIVE) can be
estimated using the equations in Table 2.
Figure 12 shows how the supply current increases from
IS(IDLE) as the input frequency increases. The increase is
smaller at higher NDIV settings.
