Part Number: DRV8872EVM Other Parts Discussed in Thread: DRV8872-Q1 Hello supporting team,
Could you tell me why duty cycle range of DRV8872EVM is different from that of DRV8872-Q1?
I saw [It is capable of an approximately 25-kHz output that can be adjusted…
Part Number: DRV8251 Other Parts Discussed in Thread: DRV8872 , , DRV8872EVM ,
Both DRV8872/DRV8251 have a DDA|8 package.
Can a DRV8872 PCB (like the DRV8872EVM below) be used "as is" with DRV8251 ? I looked at the DRV8251EVM schematics as…
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…
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…
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…
