Part Number: DRV8876-Q1 Belows are schematics for DRV8876-Q1
There's no software, only input 12V to VM pin
PIN(VM, VCP, CPH) = 12V
Q1) What is the normal voltage range of VCP?
12V of VCP is right?
Q2) What is the normal voltage range of CPH…
Part Number: DRV8876-Q1 Hello team,
Can I ask a question for motor selection?
The system configuration is as follows, but there is a current limit to 2A for input power.
: : VBAT (12V/ 2A: current limit) -> Boost IC (24V) -> Motor driver (DRV8876…
Part Number: DRV8876-Q1 Other Parts Discussed in Thread: DRV8876 Dear, TI support Team. I want to switch the rotation direction while inputting PWM from the microcontroller to the driver IC in "PWM control mode".
In that case, do I need to connect…
Part Number: DRV8876 Hello Team,
Please help me out with your valuable suggestions and feedback. The design is still in the theoretical phase. It is known that system level testing is essential for the best case scenario performance. But I am looking…
Part Number: DRV8876-Q1 Other Parts Discussed in Thread: DRV8876 , , DRV8872 I was trying to do simulation for DRV8876 in LTspice giving inputs at IN1 and IN2.Whatever the input condition is I am only getting high on OUT1 and OUT2 pins. I have tried the…
Ryan Kehr said: Is there any update on this? Please click RESOLVED if issue is resolved.
Ryan,
Yes, the issue has been resolved. The problem was caused by the BEMF of the third motor, not the two motors controlled by the DRV8876. We have two solutions…
Part Number: DRV8876 Hello,
I am trying to use the PSPICE simulation model of the DRV8876 for current limiting/regulation purpose. See my schematic below:
So whatever the value of the resistor installed on the IPROPI, I cannot change the current limit…
Part Number: DRV8876 Hi expert,
I would like to know whether DRV8876 supports bus short circuit detection ?
TI how much BDC drivers support bus short circuit detection? Including industrial and a utomotive.
Many thanks~
Part Number: DRV8876EVM Other Parts Discussed in Thread: DRV8876 , DRV8876-Q1EVM Hello,
I was looking to get an EVM for the DRV8876, however as they are out of stock, would I be able to use the DRV8876-Q1EVM for an identical evaluation or are there any…
Hi Jacob,
Jacob Thompson said: Also, can you confirm if the chip in question is the DRV8874 or DRV8876?
It's DRV8876.
The nfault trigger signal is as follows:
CH1-current signal/CH2- 24V supply/CH3- nFault signal
The customer currently suspects that…
