Collector sense and dimensioning of Rth
SCALE drivers do not use a static reference voltage to compare the voltage at the
collector. Instead, the reference is used as shown in Fig. 5.
Table 1 Reference resistor, reaction time and turn-off threshold
Notes on Table 1
The values for “Vth1” and “Vth2” are listed in Table 1 as a function of the reference
resistance Rth.
The value in the “Vth1” column corresponds to the voltage threshold after the response
time has elapsed.
The value in the “Vth2” column corresponds to the voltage which is set up statically
across the resistor Rth. This static value is typically reached after between 10 and 15µs.
