Part Number: DRV8424 Tool/software: Hello.
We would like to drive one of multiple stepper motors, each with a separate DRV-chip. Only one motor is needed to be driven at a time. The others can be de-energized. To save MCU pins, DIR, STEP, VREF and nFAULT…
Part Number: DRV8212P Other Parts Discussed in Thread: DRV8837 , DRV8212 , Hi team,
My customer is asking if there's a SPICE model for the DRV8212P, claiming he can't find one on the TI website or in PSpice for TI. I see that there isn't one available…
Hi David,
We bought some DRV8210, DRV8212 and DRV8220. for the moment we only tested DRV8210, DRV8212 and it is not a solution because (same as in your tests) it still consumes a few mA of leakage when in sleep mode and outputs are connected to high.
This is…
Hey Abhi,
Yes, this should wor, though I would be worried about any voltage dip under load conditions if the voltage dropped below the undervoltage condition.
I recommend you consider the DRV8212 or DRV8212P - its minimum VM voltage is 1.65V, has higher…
Other Parts Discussed in Thread: DRV8212 Hi,
I am wondering where can I find the current and voltage sampling time of DRV8212 C2 kit for the ADC results. Are these two sampling times are same or different?
And also the base currents in the BLDC sensor…
Hi Ryan,
Thanks for your reply. Our customers' EE is toothbrush. The space of PCB is limited. They have made their DRV8837EVM and plan to test.
Here is their schematic. They use M_PWM1 to control both DRV8837. Will it still have the risk of shoot…
Part Number: DRV8212P Other Parts Discussed in Thread: DRV8212 The datasheet of DRV8212 suggests using bulk capacitor. How can we arrive at a value for this capacitor? and is there any reason for why only a 0.1uF ceramic cap is added in parallel?
I have…
Hi Conrad,
The DRV8212 may run fine at 175 kHz but we do not guarantee it will work all the time or what the long lasting effects will be. TI only guarantees proper operation up to 100kHz.
Regards,
Pablo Armet
Unfortunately, this is the only driver capable of PEAK and HOLD current regulation. If you will keep the HOLD and PEAK currents at the same level, I recommend the DRV8212 or DRV8251 as a replacement.
