DRV8801A-Q1: supply voltage and output voltage relationship

Hi, if we power the DRV8801 from 24V, would the output be able to drive +-/12V?

Thanks,

Jeramie

    Hi Jeramie,

    As with any full-bridge the load will see the full 24V (almost) across it for a supply voltage of 24V. The polarity across the load changes depending on which arm is conducting. What is the expectation for +/-12V? Would the expectation be with reference to GND, +12V on one output and -12V on the second output? This would not be the case. Thanks.
