GENERAL DESCRIPTION
The IK6019A is a high-voltage, high-current array containing eight open drain LDMOS. The
drain-current rating of single LDMOS is 250mA. Suppression diodes are included for inductive load
driving.
The IK6019A is supplied in 16 pin plastic DIP packages with a copper leadframe to reduce
thermal resistance. The IK6019A is available also in small outline package (SO-16).

Notes
1. Stress beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the
device. These are stress ratings only and functional operation of the device at these or any other
conditions beyond those indicated under “Recommended Operating Conditions” is not implied. Exposure
to absolute-maximum-rated conditions for extended periods may affect device reliability.
2. Human body model: equivalent to discharging a 100 pF capacitor through a 1.5 kΩ resistor.

IK6019A
FUNCTIONAL DESCRIPTION
The IK6019A provides 3 stepping modes setting as shown in the table below. The stepping mode depends
on signals DIR1 and DIR2 at the falling edge of the first pulse of IN1 (IN2):
DIR1
1
1
0
DIR2
1
0
0
Stepping mode
Single stepping
Half stepping
High torque stepping
The second pulse of IN1 (IN2) (time from falling edge till raising edge) determines the duration of the output’s
operation, whereas the next time from raising edge till falling edge sets the delay time between output
channels in depend on stepping mode.
After changing direction (DIR1 (DIR2) falls from “1” to “0” or rises from “0” to “1”), outputs OUT1_1 to
OUT1_4 (OUT2_1 to OUT2_4) are turned off and will be switched at the next pulse of IN1 (IN2) in according
with stepping mode.
If the input RESET changes the level from HIGH to LOW, all outputs and internal triggers are turned off. After
returning the HIGH level to the input RESET, it is needed to determine the stepping mode again as was
described earlier. Note: in during of changing the RESET level from LOW to HIGH the IN1 (IN2) level must
be HIGH.
Please, for more detail description of operation see the section TIMING DIAGRAM.
