DRV110: Parallel Operation

user6281095

Part Number: DRV110

Hi there,

In my project, I have 4 solenoid injector to control. I would like to use one DRV110 to driver one low side MOSFET so 4 DRV110 will be used. I would like to know what is the best practice to operate these 4 DRV110 synchronously? same peak and hold parameters will apply to each of them. Is possible to joint connect PIN: KEEP, HOLD, PEAK, OSC together?

Best regards,

Mike

    Hello Mike,

    Each DRV110 Keep;Holp;Peak;Osc  needs to have a dedicated component, pins can not be controlled by same passive R and C.

    The external passive components set the internal current for the internal comparators, with a common one DRV110's will fight one each other
