Part Number: DRV8323R Other Parts Discussed in Thread: DRV8306EVM , DRV8306 , DRV832X
Hi Team,
I'm posting this in behalf of the customer.
I read many different questions about this driver (8320 family) but I wanted to ask related question on the…
Hi Joey,
You have a few options here to replace the BD63002, which uses a single PWMB input and Hall sensored feedback to commutate a 3-phase BLDC motor up to 24V.
If motor power is under 70W, I recommend the MCT8316Z (integrated MOSFET 3-phase simple…
Fares,
I'm a little confused about what you are wanting to do. How do you want to drive DRV8323 with UC2625? Both devices are intended to drive external FETs to drive a motor. Are you looking for a device that takes hall inputs for the gate driver…
Hello Adam,
Thanks for your question, and welcome to the world of BLDC motors! Let me be the first to tell you that this is a place where many engineers don't feel very equipped or knowledgeable when starting out.
I do have several BLDC motor trainings…
Part Number: DRV8161
Tool/software:
What are the advantages or using a BLDC Smart Half-Bridge Driver over a Traditional Half-Bridge Driver?
A smart half-bridge driver offers significant design and cost (space and BOM) savings as opposed to a traditional…
Other Parts Discussed in Thread: DRV8302 , DRV8306 , DRV8328 , DRV8311 , DRV8329 , DRV832X , DRV8323 , DRV8353 When using a Brushless-DC motor driver with a Hardware interface versus a SPI interface, there is a trade-off of having simpler device setting…
Hi Emanuel,
I am glad to hear that changing the DRV fixed the issue!
1. When SHA and GHA are equal as shown in the waveforms you provided, the MOSFET is off and the phase is in Hi-Z mode (both MOSFETs of half bridge A are off). The SHA voltage goes…
Hi Daniel,
It should be fine to route the differential traces under the gate traces as long as:
1. They intercept the gate traces at 90*.
2. Preferably having a ground layer that is separating the gate traces and the differential traces. If you…
Hi Yardi,
Thank you for your questions!
You mentioned that you are targeting 100ns MOSFET rise/fall time. A few important notes:
1. The MOSFET rise/fall time refers to the VDS rise/fall time, not the VGS rise/fall time. So to properly understand…
Hi Chase,
I discussed with the team and they recommended using a 47nF capacitor for the charge pump. There were some reasons why we initially suggested a 10nF capacitor, but those issues have since been resolved so now the 47nF capacitor is the recommended…
