Other Parts Discussed in Thread: DRV8837, DRV8835


Dear Technical Support Team,

I have a question about DRV8837 and DRV8835

1.)DRV8837 datasheet says Iout is 1.8A(max). Is it DC specification?

2.)How is the consumption current of Ivcc for Sleep mode and No PWM ?
   Datasheet says that Ivcc is from 450～2000μV, but I don't know that it includes Sleep mode and No PWM.

Best Regards,
y.i

    Hi Y.I

    1.8A is for motor peak current. It is DC in BDC motor but quite close to the limit of the device. Good layout and heat dissipation must be needed.

    Ivmq is 30nA and Ivccq is 5 nA. Not clear about your statement.

    Hi Wilson,

    Thank you for your reply.

    I insert my comment to your answer.

    >Ivmq is 30nA and Ivccq is 5 nA. Not clear about your statement.

    I'm sorry that I didn't describe the detail. I'd like to know IVCC(No PWM) and Ivccq(VCC sleep mode supply current) for DRV8835 .

    DRV8837 datasheet has these spec , but DRV8835 datasheet dosen't have these spec.

    Best Regards,
