In all the captures provided I see the output channel has voltage as the units so I want to make sure, is this the current through the load? If it is not, if you have a current probe can the current be captured with the current probe so the load current…
Part Number: DRV8873HEVM Other Parts Discussed in Thread: DRV8873 Tool/software: Dear Ryan,
We are still using the DRV8873HPWPR(Q1) and we want to drive it by PWM (PH/IN2, pin 8) therefore two questions:
1. if we go to PWM is it than necessary to…
Part Number: DRV8243-Q1 Other Parts Discussed in Thread: DRV8873 Tool/software: Hi team,
Since DRV8243 has high-side current sensing, how it senses motor current of whole cycle? customer concerns that DRV8243 can't get motor current for whole cycle…
Part Number: DRV8714-Q1 Other Parts Discussed in Thread: DRV8873 Hi team,
Do we have max and min PWM duty cycle limitation for high frequency operation (60khz) for DRV8714 and DRV8873 and why? Will it influence the CSA accuracy ?
We have this question…
Part Number: DRV8873 Other Parts Discussed in Thread: DRV8245-Q1 ,
1) In [6.5] the datasheet lists possible ITRIP values as 3.85, 5.4, 6.5, 7A. However in [7.3.1.3 , Table 8 ] the values are 4, 5.4, 6.5, 7A. Which one is correct?
2) In DRV8245-Q1…
Hi Annie,
Thanks for the information. First let me comment on 2 and 3.
2. The final comment was " Assuming the voltage and current requirements can be met with the DRV8871/2, it should be able to control a bistable latching solenoid.". But there was…
Part Number: DRV8256 Other Parts Discussed in Thread: DRV8251EVM , DRV8251 , DRV8210 , DRV8873 , DRV8243-Q1 We are designing motor circuits using the DRV8256. Which circuit should I use: high-side or low-side to measure the current flowing through the…
Hello!
Unfortunately we can't recommend this. However, we have drivers capable of 10A peak and beyond.
DRV8873
DRV8243-Q1
DRV8244-Q1
DRV8245-Q1

Hey Maurits,
Correct me if I'm wrong, but would this application be better suited with Current Sensing or Stall Detection instead of Open Load Detection? Current sensing so that you could detect when it reaches the end by a spike in current.
Also…
Part Number: DRV8873 Other Parts Discussed in Thread: DRV8244-Q1 , DRV8245-Q1 , DRV8343-Q1 Hi,
Currently, we are using Automotive H- Bridge DRV8873HPWPRQ1 Motor driver IC in our current design at peak drive current of 8A. Here we need your support for…
