Part Number:DRV8353
Dear Team,
after esolve the problem with demaged ICs I now test more and more and try to get a current output from the internal amplifier. I run with a PWM of 4 kHz and 33% duty. Power supply say 2,5 Ampere curent flow into the system. But the current amplifier from DRV8353 show at osciloscope maximum output at 3,3 Volt. Gainsetting is 10 V/V. I use the 7 mOhm Shunt at the EVAL Board.
I also tested the INA240 with 3 mOhm Shunt and get also full output 3,3 Volt at 2,5 Ampere Input!
How did I measure a real current value?
Regards,
Peter
