DRV2510-Q1: can the 2510 drive multiple actutor by parallel connection

Part Number: DRV2510-Q1

hi sir

can I use one drv2510-q1 to drive 3 actutor simultaneously？

the actuator is same type , but may have part to part variation in resistor.

what's risk about this method?

    Hi,

    The minimum load impedance of DRV2510-Q1 is 1.5 Ohms. If the parallel resistance of 3 actuators is more than 1.5Ohms then is will be safe to drive them in parallel.

    if the difference in the actuator resistance is significant, then the vibration may be stronger on the low resistance actuator.

    However, some variation of +/-10% or so. should not be be significant enough to notice a difference in vibration strength

    Regards,
