Sirs,

On P/N DRV8412 for Pin 14 signal OC_ADJ, what is the Max input current over temperature of -35C to +125C?

We need to know this for our Reliability analysis. Please provide an answer today. Thank you.

Hi Charles,

We will investigate and reply no later than tomorrow.

Hi Charles,

The typical current is 1.24V/R_oc. The 1.24V should stable across temperature, but for worst case we can assume 1.5V (+20%). This would mean approximately 68uA with a 22kOhm resistor. The resistor variation will also affect the current.

If you want to be very conservative, you can use 100uA.
