Part Number: DRV8837 Dear team,
For DRV8837 and DRV8837C, do you have the Rdson when Vin at 3V~4.2V? We saw from the datasheet of figure 3 only see the specific value at 3V,5.5V.
Also, could you give more detailed instruction of Tretry? Will tretry…
Part Number: DRV8837C Other Parts Discussed in Thread: DRV8837 , Hello
Could you help provides DRV8837CDSGR's Marking info, and explain their respective meanings. thanks
Part Number: DRV8837C Dear,
We use DRV8837C to drive valve. When the power is shut down, DRV8837C need to keep working to close valve, so we use a 3.3F/5.5V capacitance to maintain power. We do an experiment: valve rotates forward for 200ms and then…
Part Number: DRV8837C Hi TI,
My customer drives BDC motor with discrete circuit.
So we promoted motor driver DRV8837C.
The problem is drive current is increased compare with discrete circuit. (motor is same)
Please let me know the reason.
Ed,
We do not have a dedicated Spice model for the DRV8837C. Please contact your local TI sales rep of field engineer to request that model.
Regards, John
Part Number: DRV8837C Other Parts Discussed in Thread: DRV8832 , DRV8832EVM , Hi Team,
I am working with a customer on narrowing down the best part for their application. Right now we are debating between the DRV8837C and DRV8832. The intended use is…
Part Number: DRV8837C application: bike lock
2 chip is tested ,after 1000-times test,one is burned out.
vm=4.2V, Iout<550mA

Just read in the datasheet, that the IC will disable itself when to much current is flowing. Are there any alternatives to this IC, which implement the same functionality but additionally regulate their output current to a maximum value instead of shutting…
Hi Susan,
We have not seen this before.
Can you clarify "the power up moment"?
Does this mean VM power up , VCC power up, nSLEEP rising to exit sleep?
Can you provide a timing diagram of the power up moment.
Also can you explain what is meant…
Part Number: DRV8837C Other Parts Discussed in Thread: DRV8848 Hi
Is it valid OCP function when the motor starts up?
We require 1A output constantly, but 3A may be required when start up.
Can we use DRV8837C?
BestRegards
