Hi,
I am using DRV8844 driver IC in my application. I used micro controller's pwm interface to drive output. Output works fine.
At normal steady high output, short circuit works but is not working at 100KHz pwm frequency with 50% duty cycle.
In application note www.ti.com/.../slva505 you have shown results for output enabled with direct short across output but what happens for pwm output at such higher frequencies. Even though current exceeds it should get thermally shut down.
And also you haven't mentioned maximum pwm operating frequency for the same, I would like to know that.
