Other Parts Discussed in Thread: DRV8256, DRV8245-Q1
Hi
We are using the part DRV8873-Q1 in our automotive design. The motor driver is used for controlling window up and down motion in cars.
While calculating junction temperature using the datasheet as per section 8.2.1.2, we observed that junction temperature exceeds 150 deg for an rms current greater than 5A.
We have a requirement for continuous current of 7-8A and peak current of 10A. But 7A is exceeding the junction temperature limit of 150 deg. We have connected the motors to 12V in our design.
Please let us know if this motor driver DRV8873-Q1 is capable of driving loads of 7-8A?
If yes, why is it exceeding the max junction temperature mentioned in datasheet?
Regards
Prema
