NOTES:
1.Ramp up V

from 1.0 to 5.0 V in 0.1 V increments. Record V
in(–)
when I
CR
goes positive and convert to % of V
CC
by dividing by V
CC
.
2.Ramp up V
in(–)
from 3.0 to 10 V in 0.1 V increments. Record V

goes positive and convert to % of V
CC
by dividing by V
CC
.
3.Ramp up V

in 0.01 V increments. Record V
in(–)
when I
CA
goes positive. V

NOTES:
1.The falling edge of the V
signals a charge command, while the rising edge signals a spark command.
2.During start mode, stall conditions are prevented.
3.During a stall, the coil is discharged slowly and a quick charge and spark occur on the next spark command.
