Part Number: DRV8307 Other Parts Discussed in Thread: DRV832X , DRV8711 , TIDA-01227
Hi,
I would use a low Rdson MOSFET Type (<2mOhm) with a Gate Charge of 120nC. For fast switching I need a Gate Current of 1A...2A. Regrettably I only found in the Datasheet…
Part Number: DRV8307 Hi Team,
The customer is using DRV8307. He has some qusestions as belows.
Q1: Locked Rotor question:
The customer refer to 7.3.11.6 Rotor Lockup (RLOCK) of the datasheet. If the motor is needed to stop operation normally, is this situation…
below are the graphs for your reference Tested tested with TI DRV8307 EVM board. input PWM is from on-board pwm generator IC555(25kHz frequency). Power supply 24V adapter type SMPS (CE complained)..
Range is 30M-1GHz
Peak on V :
Peak on H :
Thank…
Part Number: DRV10970 Other Parts Discussed in Thread: DRV8308 , DRV8307 , I am in the process of selecting a motor driver/controller and I have narrowed it down to the DRV10970, DRV8308 or DRV8307. I need to drive Faulhaber 2-pole BLDC motors from 1000…
Part Number: DRV8307 Hello,
I have a problem with the DRV8307 driver that I used in my application.
The problem is that when I start the engine, until the LOCKN signal occurs, everything is ok. At the LOCKN signal, the motor will suddenly brake (not completely…
Hi,
The problem is still there, i have attached the waveforms for fault, lockn, hallout pins. All hall sensors are working fine.
Probe 1 is lockn, Probe2 is hallout, Probe3 is fault. The moment hallout stops is the point where the motor is stoped due…
Part Number: DRV8307
Would someone mind reviewing the attached RevB schematic and gerbers for this updated Motor Driver Board?
My issue with this revision: I need to drive the motor at 5000 RPM, but the driver board seems to be maxing out at around 2400…
Part Number: DRV8307 The motor spins up and the 8307 outputs LOCKn. Then the device loses lock and coasts down to almost stopped. then it starts again on its own and repeats the process. These repeats until I stop the motor. The repeated stop and start…
Part Number: DRV8307 Hi,
I'm beginner for motor driver, and have a problem with using TI's DRV8307
The symptom is as below.
-> when repeat start and stop in turn, discover the symptom that do not start.
: The motor emits a high requencty sound…
