    Helmut, It appears, as you mentioned, that we are out of stock for the samples. The only solution would be to order an EVM. https://www.ti.com/tool/DRV8872EVM Regards, Ryan

    Hi Barry, Sorry for the delay. I modified the DRV8872EVM to remove the nFAULT diode and 10k pullup to 5V. I then connected a 10k pullup to 2.5V. The device acted as intended. The voltage on nFAULT was 2.5V. As the VM voltage dropped below the UVLO…

    Hi Simen, There is no specific reason that >50% duty cycle is required when using the DRV8872. Can you provide a little more information to help narrow down what the possible reason? Are you using the DRV8872EVM? Can you provide scope captures of…

    Hi Adrian, Of the three, I would start with the DRV8872. The DRV8872 is the simplest of the devices, with fewer external components. The DRV8872 also can operate up to 45V, so it could handle future applications. The DRV8872EVM can be used to evaluate…
