Tool/software:
Hi team，
Can you provide the efficiency curve of DRV2605 - Q1?
We want to know the curves corresponding to current and power, with an output voltage of 1.2 V and a current < 100 mA.
We hope to evaluate the thermal loss of the IC.
Thanks
Xiaoxiang
Hi Xiaoxiang,
We do not have efficiency data for a specific output voltage and / or current but we have the below plots. For LRA mode a 25 ohm load was used and for ERM mode a 10 ohm load was used.
We have this app note as well which goes over haptic energy consumption that may be useful: https://www.ti.com/lit/an/sloa194a/sloa194a.pdf?ts=1737560450067&ref_url=https%253A%252F%252Fwww.ti.com%252Fproduct%252FDRV2605L-Q1
We also have the following thermal information in the datasheet.
Regards,
Sydney Northcutt
