Part Number: DRV8803

Dear Support Team,

I have some question regarding DRV8803PWP.

  • Can it support 1A load current for four channels on at Ta=75C?
  • Can it support 1.2A inrush current for four channels on at Ta=75C ?
  • How much current does it support at two channels on at Ta=75C ?

Best regards,

Hiro Takahashi

    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.
