Part Number: DRV8873-Q1 Tool/software: Hello,
In my application, I'm using DRV8873H to drive a resistive load with high-side configuration: output is connected to resistive load to GND.
My resistive load is about 6Ohm .
Driving signal: 200Hz with…
Part Number: DRV8873 Tool/software: I am writing to inquire about motor driver ICs with reverse voltage protection.
I recently designed a circuit using the DRV8873 to drive a motor. However, I encountered a problem where the voltage on the VM power…
Part Number: DRV8873-Q1 Tool/software: Hi
We are using DRV8873-Q1 in our design. We are measuring 1.4V at Iprop pin. We are using 390 ohms sense resistor as per the below schematic.
Now while using the formula and checking for current, we are getting …
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…
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 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 Although OCP is programmed at 4A, no limitation occurs with 5.7A load.
I use the SPI version, program the lowest current limit, but at 13.5V through 2Ohm power resistor I get 5.7A and no OCP, what am I missing ?
Below are the values…
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
Maurits…
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!
