Other Parts Discussed in Thread: DRV8871
Dear reader,
On a existing PCB design I use the DRV8840. I would like to drive and regulate a thermal pad which is a pure resistive load (120ohms on 24V supplly).
My preliminary tries are failed. the Ichop set is >500mA and the duty cycle is not 100%. below
Is there a limitation explaining that result?
Thanks in advance for your support!
Regards
