Using DRV2667 piezo haptic driver with several piezo actuators

Other Parts Discussed in Thread: DRV2667

Hi.

I am considering a design of a keypad with a haptic feedback using piezo actuators. It is desirable to place actuator under each key.

Is there a way to use one driver DRV2667 per several piezo actuators (only one actuator can be active in each moment) or I will need separate driver for each actuator?

    I'm working on something similar. Without any fancy, high-voltage switching to selectively enable actuators, it looks to me like it will take one '2667 each.

    A further question is separate addressing of devices.

    Every DRV2667 has the same I2C address and I don't see any way to disable the I2C and leave the rest running.

    Thank you, John.

    One DRV2667 per sensor is too expensive for my device. I am thinking of using one DRV2667 with something like
    Supertex HV509 or HV513

    There was no much time to check it, so can not say, will it work.

    Wish you success,

    Alex
