DRV595: The maximum output of the DRV595

Lacey Lin

Part Number: DRV595

Hi team,

For the DRV595, what's the maximum differential output voltage?

Does the maximum differential output voltage relate to the supply voltage and the load?

I have find the spec in the datasheet, the datasheet shows the output differential voltage can't be larger than 12V.(as below)

So I don't know if this spec is related to specific condition.

Can you help to provide the method to know the maximum differential output voltage? such as the PVDD=12V, the output load is 8 ohm.

Lacey

Thanks a lot!

    Hi Lacey,

    The table captured by you has the following testing conditions: PVcc=12V, hence you see the output voltage of 11.85V.
    In fact, the output voltage will near PVcc as you thought. For your applicaiton, Rds(on)=60mohm, you can calculate with PCB trace resistance by Ohm law.
