Part Number: DRV2605 Dear Team,
I am experiencing a problem where DIAG_RESULT and FB_STS in diagnostic mode goes to 1 only once in several times, otherwise DIAG_RESULT goes to 0 (normal). Even when DIAG_RESULT and FB_STS go to 1, the vibration works fine…
Hi Jerry,
there are some differences in the register maps for these devices.
the registers related to the LRA calibration should be the same between devices (0x16-0x1A) however there are some differences.
your firmware may be writing to some incorrect…
Part Number: DRV2605 May I ask whether the settings of the registers 0x16, 0x17, 0x1A are mainly determined by the last settings, or is it recommended to determined in the Auto-Calibration stage?
1. Will the settings set in the Initialization stage be…
Part Number: DRV2605 1. The customer considers to control two groups of DRV2605 with the same i2C which depends on the control of the DRV2605 EN pin
. According to the datasheet description, when one DRV2605 EN pin is set low, it will not respond to the…
Part Number: DRV2605 If I change EN 1→0, the DRV2605 enters shutdown mode.
And then I change EN 0→1,the DRV2605 will enter stand by mode as the picture shows.
And then, Whether will the DRV2605 automatically enter active mode? Or I must write…
Part Number: DRV2605 Hi TI support
Does DRV2605 support boot buzz when the mobile is still not power on?
By that time, no calibration, no I2C clock, could we send waveform through I2C and vibrate?

Part Number: DRV2605 Other Parts Discussed in Thread: DRV2604 What I want to do :
- Store the amplitude of my control in a register (RTP mode).
- The pulse width in which, the LRA motor executes this amplitude, which is also stored in a register.
The…
Part Number: DRV2605 Hi team,
We are working with DRV2605 haptic driver on linux kernel 5.15.60 with IMX8MP processor
Driver path : drivers/input/misc/drv260x.c
We observed some vibrations when the driver gets invoked during bootup. But after bootup we…
Part Number: DRV2605 I'd previously written in about "4 DRV2605YZFR parts on the same I2C bus?"
We went forward with our design, made a prototype and wrote the firmware. Now we are finding that the EN pin being low does not prevent writes…
Part Number: DRV2605 Hello, The DRV2605 data sheet says that when the in/trigger pin is not in use, it "should" be tied to ground. Can I get clarification on this? If I float this pin, it would allow a lower technology class on my PCB by letting…
