Part Number: DRV8908-Q1

Hi team,

Even though we use parallel mode, can DRV890x-Q1 detect the overcurrent and open load per channel?

Thank you.

Hirata-san,

Yes, the monitors are still active. In parallel mode, the current is just shared between connected outputs. So, it current is 2A, 1A will flow from each output. When OCP current limit is hit for either output, protection will activate. It is not a perfect current sharing, so one channel may take slightly more current than the other.

Ryan
