  DRV2625: DRV2625 VDD versus LRA waveform Vpp

  TI Thinks Resolved

  Part Number: DRV2625 Hi We set overdrive voltage = 3Vpeak as attached excel But we find when we change DRV2625 VDD voltage, the waveform Vp/Vpp also change as below table Is it normal? Since as I know the Vp should limit at Vpeak setting Thank...

  DRV2625: DRV2625 VDD current have negative

  TI Thinks Resolved

  Part Number: DRV2625 Hi We check DRV2625 VDD current with driving LRA vibrator We fine there is negative current part when we using current probe to measure Is it normal? If yes, how do we estimate VDD current? Using Vpp(pk-pk) or use Vp(max) ?...

  RE: DRV2625: Waveform LIbrary TS2200 in ROM but where can I find information on the 127 waveform identifiers in Library B?

  thanks, I didn't see the table in my document searches. There is so much information in the register descriptions, and they keep mentioning the waveform index positions, perhaps a direct reference to this table would help people navigate your documents...

  RE: DRV2625: Calibration

  Hey Olin, It is best to check the DIAG_RESULT flag as well because it is specific to indicating the completion of the auto-calibration, whereas the PROCESS_DONE flag is generic to all processes. But they are both supposed to be indicating the same thing...
