Hello! I am Eren,
Firstly I want to say thank you! We tried your suggestions and we took some way on the project, but now our main problem is sometimes we start the motor but hasn't any move and drv10970 evm module open the led 2.I forced the motor for…
Part Number: DRV10970 Hi Team,
The customer is experiencing below issue and needs your help.
Fixed PWM duty cycle for DRV10970, output is 200Hz, but output frequency always fluctuates between 188-202Hz. Customer would like to know what could be the cause…
Part Number: DRV10970 Hi Team,
The description in the data: Rotational direction can be changed while motor is spinning. The device takes t LOCK_EX time before reversing the direction.
The customer's understanding is that t LOCK_EX must be waited for…
Part Number: DRV10970 I've looked over the datasheet and it simply should, but apparently does not say. I have an application where we're using these little tiny BLDCs with gear drives. They need to crank 13k RPM. Going too slow can blow the motor…
Part Number: DRV10970 Hi team,
The customer is experiencing below issue and needs your help.
1. In what form does the FG output speed feedback of the DRV10970 be output to the MCU?
2. For example, takes STM32 as an MCU. In what form does the FG pin output…
Part Number: MCT8315Z Other Parts Discussed in Thread: DRV10970 , , MCF8316A Hello,
We are developing a product for an application that requires high control performance with low power. We aim to drive a PMSM (Permanent Magnet Synchronous Motor) in the…
Part Number: DRV10970 Hi, Our customer wants to know if the value for VILIM_THR and ACL would stay the same for VM=5V or 6V. On the datasheet, it shows that this vales are for VM=12V. I would appreciate if you could confirm the values for VM=5V or 6V. In…
Part Number: DRV10970 I'm submitting a design to UL, and they are asking for a description of how the voltage boost functions. It appears to be a simple capacitor boost circuit, but they need more details to be sure how it might fail. They need to…
Part Number: DRV10970 Other Parts Discussed in Thread: DRV8320 , DRV8308 I'm starting a new 3PH BLDC motor drive application and don't have time for many design iterations. I'd like some advice on best controller families to start with to avoid…

Hello,
I purchased DRV10970EVM to test my 3-phase sensored DC motor and it worked for couple of seconds and then the on-board fuse popped up and it stopped working. There…
