Part Number: DRV8308 Other Parts Discussed in Thread: DRV8307 Hi all Would you mind if we ask DRV8308? Could you let us know the LOCKn assert condition(LOCKn=Low)? The datasheet shows "After a constant speed is reached, the LOCKn pin is pulled low and…
Part Number: DRV8308 Currently we are using DRV8308 to control Blower "Brushless DC Motor" to control air flow the motor is working smoothly and transitions is smooth
our main problem now is Rise and Fall time while changing speed we are using Driver…
Part Number: DRV8308 Dear TI-Team and friends,
since some time we use the DRV8308 at an 18 Volt BLDC motor. Sometimes (less then 1% of your PCBs) we see burning parts and pins on the DRV. Please see attached picture.
What could be the problem here…
Good morning.
I noticed one weird fact: when I set the hall polarity bit on register 6 the motor spins in the opposite direction, is that normal?
The power consumption is very high in basic mode even at low rpm whether the hall polarity is set or…
Part Number: DRV8308 Hi team,
I am using DRV8308 to control a brushless motor. The rotation of the motor is controlled by "Clock Frequency Mode". I am inputting a 150Hz square wave to CLKIN, but the rotation of the motor is not so stable. In such a…
Part Number: DRV8308 Other Parts Discussed in Thread: MCT8316Z , DRV8306 Hi, we have designed and produce a pcb board for DRV8308 under respect to reference design of DRV8308 from TI
We use LTC6992 for PWM generation. But the BLDC dont wamt turn.

Part Number: DRV8308 Other Parts Discussed in Thread: , CSD18540Q5B HI all
I am driving airfan mfa 0500 BLDC blower using drv8308 driver, i am using stm32 to program it and to generate the pwm and control the drv8308 the issue is at 100 percent pwm…
Part Number: DRV8308 Hi,
DRV8308 stops communication via SPI after ENABLE signal is aplied (PWM mode). I have to restart driver and it starts communication again.
I did check voltages against Your Dev KIT and they are the same (like VCP, VREG, and…
Part Number: DRV8308 Good day,
We are developing a light vehicle using the DRV8308. it has performed well so far,except for..
The lock pin, initially I assumed it goes low when the clkin frequency matched the fgout frequency but that doesn't seem…
Part Number: DRV8308 Other Parts Discussed in Thread: DRV8343-Q1 I am using Pspice for TI. DRV8308 is unavailable in pspice for simulations. Where can I get the spice model
