Table 2. Static Electrical Characteristics
Characteristics noted under conditions 7.0 V ≤ VCC ≤ 18 V, -40°C ≤ TA ≤ 125°C, GND = 0 V unless otherwise noted. Typical
values noted reflect the approximate parameter means at TA = 25°C under nominal conditions unless otherwise noted.

Notes
7. Advance Threshold Voltage is the positive (or negative) going voltage on Advance necessary cause the Dwell Control voltage to positive
(or negative) going transition 2.0 V respectively. It is expressed as VTH±(A) = VB + VX where VB is the Bias Voltage and VX is the additional
voltage necessary to attain the threshold.
8. Bypass Threshold Voltage is the positive (or negative) going voltage on Bypass necessary cause the Dwell voltage to positive (or
negative) going transition 1.5 V respectively. It is expressed as VTH±(BP) = VB + VX where VB is the Bias Voltage and VX is the additional
voltage necessary to attain the threshold.
9. Increasing voltage on Current Sense which when attained will cause Dwell to transition low to 1.5 V with a 10 mA load.
