- I'm using the LMP8481 to measure the current of a PWM servo system (driven by DRV8881)
- The supply voltage to the circuit is between 20V to 35 VDC
- There's an ambiguous note at the data sheet (8.3.6 Low-Side Current Sensing), which warns about low voltage (<4v) usage
- Should I be worried using the LMP8481 in my application ?
- Another question, is it better to power that IC from the servo PSU, or from a separate (less noisy) 5V PSU ?
Thanks
