DRV2625: Diagnostics and Calibration both failed

Part Number:DRV2625

Hey,

I am evaluating, the DRV2625EVM-MINI Evaluattion borad  with an Linear Resonance Actuator whish specification are:

-Vibration Frequency: 2.5Grms@100Hz (Fact)

- Rated Voltage,2.23Vrms

-Response time <30ms

-power consumption <300mw@2.23Vrms (Sine Wave)

Following these specifications, i have to set Drive Time to 1/(2*Fact)=5ms (see DRV2625 Data sheet at page 23). But the maximum Drive Time Allow in DRIVE_TIME Register for LRA actuator is 3.6ms (see Page 54)

to Get a Rated Votage of 2.23Vrms, I have to set RATE_VOLTAGE register to 0x64 value. The Clamp Voltage is 2.23*sqr(2) < 3.16V so i have to set CLAMP Voltage to 0x95value.

Please See attached File for other Value Configuration register that i used.

Now, when i do Calibration (1000ms) it failed with none over-current Dection, over-temperature or Udervoltage detection. Diagnostic Process Failed with none Error Detection.

Am I do something Wrong?

How can i resolve this issue?

Thanks

Th
