RE: DRV8803: Load current at Ta=75C

Hi Takahashi-san,

What is the supply voltage?

I have some question regarding DRV8803PWP.
•Can it support 1A load current for four channels on at Ta=75C?

The device cannot support this level of current.

•Can it support 1.2A inrush current for four channels on at Ta=75C ?

What is the duration of the inrush current?
What is the current level after the inrush current?


•How much current does it support at two channels on at Ta=75C ?

Approximately 1.1 Amps per channel assuming adequate thermal heatsinking.
