Part Number:DRV8847
Hello team,
is designing a system for industrial machinery. We have come up to the following devices as choices but I would like to have a suggestion from your side which suits better the job among: DRV8847, DRV8881P, DRV8872.
Specs: the H bridge will be mainly supplied by a 15V unit but there is a possibility that it could be supplied by a 30V unit too. Interface PWM. The H-bridge will be controlled so that it supplies at the load a sinusoidal current with a peak of 1.6A (in the transistors the value could be higher) and a frequency of 20KHz. Delay time between control and variation of the output should be less than 1us. Current measurement inside the MD isn't required for the normal funtioning of the device but only in case there is a fault at the load.
Price and size aren't a focus right now but of course the lower they are, the better it's for the final application.
Among the three quoted above, which do you recommend the most? Is there any other device that I missed?
Thank you and best regards,
Adrian
