Part Number: DRV10970 Other Parts Discussed in Thread: MCT8316Z Hi,
I am searching for alternative to DRV10970 - PWM controlled, sensored (3 hall sensors) three phase brushless DC motor driver with integrated FETs which is limited to 18V while our need…
Part Number: DRV10970 I have a PID controller getting velocity from hall sensor changes and outputting PWM to DRV10970. PWM frequency is 94 KHz.
With a step change in PWM to a lower duty cycle, the motor continues to accelerate for several commutation…
Part Number: DRV10970 Can you define when tLOCK_EN (0.7 sec) is applied during a direction change? I have read many other e2e posts about direction change delays, but have not seen a clear explanation of when this delay is added.
When I change direction…
Part Number: DRV10970 Other Parts Discussed in Thread: DRV10975 , MCT8316Z Hello,
I have been using a DRV10975 to drive a motor with 0.19mH ph-ph inductance and 0.5 Ohms ph-ph resistance from a 3-cell LiPo (11.1V nominal). I have been having trouble with…
Hi Vishnu,
The customer has successfully used the drv10970 to drive motor, but here's a new condition:
When using the drv10970 to drive motor to realize closed-loop PID control, the motor rotates too laggy, i.e. the motor rotates very incoherent,…
Part Number: DRV10970 Other Parts Discussed in Thread: DRV10964 Hi Team,
Can you help recommend IC for BLDC? Thanks.
Requirements are as follows:
1. Output interface: one I2C. 2. Motor control mode: constant voltage bipolar 3. Motor channel: 1 channel 4. Power…
Hi Robert,
From what you have told me, may I ask how you are configuring the lead angle settings on the MCT8316Z?
DRV10970 has Adaptive Drive Angle Adjust, see below:
"The drive angle can be adjusted to achieve better efficiency by measuring the phase…
Part Number: DRV10970 The documentation here:
https://www.ti.com/lit/ds/symlink/drv10970.pdf
appears to missing the 0 degree hall placement table on page 17 table 2 (no actual table is under it...).
Part Number: DRV10970 Other Parts Discussed in Thread: MCT8316Z Hi Team,
We have designed and developed our driver by using DRV10970 IC and also ship to customer. now customer want more driver with that IC , this IC is not avaialble.
please provide alternate…
Part Number: DRV10970 Hi
I have used this device to power a 24V BLDC motor. I have set output current limits appropriately so the chip will not be overloaded.
This works ok with 10-12V, but at low speeds torque of the motor is very low. Increasing the…
