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…
Part Number: DRV10970 Other Parts Discussed in Thread: DRV8308 We have an application for a Three-Phase Brushless DC Motor Driver. We are considering the DRV10970 but are open to other suggestions including those requiring external MOSFETs.
The application…
Part Number: DRV10970
Hi, We're having an issue where with variable speed (should be fixed) . The drive is driven by a 55 timer and the PWM input looks identical even when the motor is driving at different speeds. The motor tends to operate correctly…

Dear Sir,
The current limit in DRV10970 used to limit the motor phase current during application is controlled by connecting an external resistor to the CS pin (PIN 17). As per the data…

I have verified on bench that when changing FR pin, regardless of the times you toggle FR pin, the device always enters brkmod, waits until motor stops, waits Cretry…
Part Number: DRV10970 Hi,
I choose DRV10970 driver for Faulhaber motor EN-1226 (9W).
And I have a problem with current signal form, it's not looks like in you datasheet (see photo).
Can you confirm that I use right driver or I have to be changed…

The customer needs to select a motor drive device that should be not programmed by himself, only
be configured the…
Part Number: DRV10970 I am using DRV10970 for precision speed control of a three phase BLDC motor (FaullHauber 2610B). According to my understanding of the datasheet, when you switch/toggle the FR pin state, the motor first brakes and then reverses. However…
Part Number: DRV10970EVM Other Parts Discussed in Thread: DRV10970 , DRV10983 , DRV10987 Can the DRV10970 Evaluation Module drive a 3-phase brushless DC motor with no Hall sensors?
The motor, for a tangential blower, has only 3 wires.
Hey Avish,
Thanks for the clarification on deadband. My understanding is you are trying to go to speeds below ones you can achieve with the minimum 10% duty cycle by alternating between braking and spinning the motor through putting a pwm signal on the…
