Slot-less BLDC motor driver selection
I need support selecting a gate drive and fets all in one package without internal motor control. I'm planning to design a board with using an instaspin processor for the controls for the control of...
View ArticleRE: Multiple motor part
Thanks. I know most c2000 have 12 PWM output can drive up to 2 of the DRV 8312.Do you recommend any c2000 part that has more than 12PWM outputs?If yes can you run more than 1 instaspin on the same...

Need to drive multiple BLDC motor and looking for an IC to drive at least 2 motor. A 2 or more DRV 8312 architecture in one package will be ideal.Does TI has a part solution fro this?ThanksZack

Hi Davide, I am glad to hear you have the GUI working. If you are trying to detect stall conditions, the DRV8711 has the ability to do so. An alternative is using a limit switch (hall or optical...

DRV110
I'm currently using the DRV110 to drive a 12V Relay (OMRON G5LE). The same 12V power supply powers both the Relay and the DRV110. The MOSFET I'm using is the BSS138BKS.Here are my external setting:...

View ArticleRE: The DRV8844 high logic-level input is 5.25V?
Hi Otto, There should be no problem using a 3.3V mcu. The DRV8844EVM uses a 3.3V mcu to control the DRV8844. The inputs of the DRV8844 are high impedance (typically 100kOhm). A 3.3V mcu can easily...
View ArticleRE: The DRV8844 high logic-level input is 5.25V?
Thanks, Rick, for your fast reply. In most design, of course, we engineers like to err on the conservative side. We can design to typical specs, but the outliers can bite us or otherwise cause...
View ArticleThe DRV8844 high logic-level input is 5.25V?
The DRV8844 data sheet lists the logic-level input high as minimum 2.2V and maximum 5.25V. How can I be sure that I can switch this chip using a 3.3V microcontroller? Please advise.
