Part Number: DRV8210EVM Other Parts Discussed in Thread: TLV9051 , OPA170 , OPA171 , TLV341 The DRV8210EVM includes a circuit (not installed) for current sensing. The amplifier recommended is a TLV9051DRL, which is a SOT-553 device. I can't find the part…
Part Number: DRV8210EVM Other Parts Discussed in Thread: DRV8210
I only give 3.75V to DRV8210EVM from VM and not giving any signal to other pins including VCC_DRV. However, I measured 3.3V from VCC_DRV. My problem is why VCC_DRV would output voltage? I…
Part Number: DRV8210EVM Other Parts Discussed in Thread: DRV8212EVM , DRV8220EVM , Version A and E1 of the DRV8210EVM, DRV8212EVM, and DRV8220EVM have a silkscreen error where the "IN1/EN" and the "IN2/PH" silkscreen label placement is incorrect. The correct…
Part Number: DRV8210EVM Other Parts Discussed in Thread: TPS22916EVM When I using the other mcu to input high logic level signal into drv8210evm EN/IN1, then I measured the current output from the mcu gpio is 3.44mA average.
I think the current is too…
Hello,
I could be wrong, but I suspect this means that the motor driver is integrated into the iris mechanism now. I suspect the "DRIVE+" and "DRIVE-" are VM and GND on our driver, and CONTROL- / CONTROL+ are IN1 and IN2 on our driver.…
Hi Annie,
It looks like the table above if from the DRV8210EVM User's Guide.
The DRV8210 has three different control modes, PWM, PH/EN, and independent half-bridge. Table 4-2 shows how to drive a load with PWM control (MODE = Logic Low) on the DRV8210EVM…
Hi Mats,
That shouldn't be an issue, as long as enough power is supplied to the pins within the recommended operating range. It would be recommended to test this for yourself to verify all timing requirements are sufficient for the application.
DRV8210EVM…
Hi Juan,
The DRV8210 or DRV8212 would most likely be a suitable option for the application because of the ultra low power sleep mode specification.
After testing the DRV8210EVM in the lab, the leakage current is just under the 2mA between OUTx and GND…
Hey Henry,
Ahh I see. That should be possible. Since IN2 has a internal pulldown resistor, if you leave it disconnected then you'll be switching IN1 between HIGH and Hi-Z output. I suspect you would prefer switching between LOW and HIGH output, which…
