We're using the TLE7242 to drive a solenoid load as part of our test system. We're sending a ramp signal: 0 to 1000 to 0 milliAmps with 50 milliAmps steps and each step timed for 100 milliSecond.

We have a current sense circuit inline with the solenoid for realtime readings. However, we're getting a variation in the sensed current readings when we repeatedly apply our ramp signal.

Is there a specific order in which messages have to be sent to the chip to get it to drive the load? Is steady-state mode (feedback) automatically on?

Thank you for your help,
