Part Number: DRV8873SEVM Dears,
Customer feedback uses TI's DVR8873S chip. Eight DVR8873S chip materials are used in one product, and heat sinks are added to the front and back ends of the chips. The following tests have been carried out.
1. How…
Part Number: DRV8873-Q1 Other Parts Discussed in Thread: DRV8873 Hi experts.
I am currently using the DRV8873 motor driver IC to drive a DC motor. During operation, I have noticed that there is a reverse current flow of up to 2.3A from the VM pin due…
Hi, sorry for my late answer, I watched a cold in the meantime.
Firs of all sorry for the bad terminology, I was indeed referring to current regulation.
And you are right, the current regulation kicks in with an inductive load, seems this would deserve…
Part Number: DRV8873-Q1 Hi Experts,
DRV8873-Q1 is mass production on customer side. Could you confirm the meaning of those register? Thanks.
For OCP, there only one parameter show the OCP, Iocp= 10A, and the Tocp= 5us. But I find there are 2 faults for…
Part Number: DRV8873-Q1 Other Parts Discussed in Thread: DRV8873 Hi experts.
I am writing to inquire about the DRV8873 IC and its DVDD pin. According to the datasheet, it is mentioned that DVDD has an internal regulator.
I would like to confirm if there…
Part Number: DRV8873 Other Parts Discussed in Thread: DRV8876 I have questions about the operation of two types of motor drivers, DRV8873 and DRV8876.
I am considering the above driver in the device currently under design.
As for control, we are considering…
Part Number: DRV8873-Q1 To minimize the part number of a board, I'd like to use DRV8873-Q1 as a switch. Could this be happening? If so, is there anything I may need to know for application?
Thanks a lot!
Hey Maurtis,
Ahh okay understood, thank you for the detailed explanation!
First can you compare your circuit to this circuit in Open Load Detection in Integrated Drivers :
That application note has a lot of good info about getting OLD working
