Part Number: DRV8870 Other Parts Discussed in Thread: DRV8801A-Q1 , DRV8231A , DRV8251A hi,
Thank you for your support.
As we known, there are no products in our company to drive single-phase BLDC directly.
So I want to design the single-phase BLDC by DRV8870…
Other Parts Discussed in Thread: DRV8801-Q1 Hello All, I have 5 drv8801-q1's and I'm wondering if it is okay to connect all vpropi pins together, all nfault pins together and all sense pins through one sense resistor. Also, it is important to know that…
Hello,
This is expected behavior for the device due to input deglitchers that run from an internal oscillator that has a spread spectrum clocking scheme. You should see ~200ns of jitter.
We have some devices in our portfolio WITHOUT this feature, but…
Hi Daniel,
The DRV8801 provides the option to monitor the current through the motor winding by measuring a proportional voltage through a sense resistor. Below is a screenshot o f the datasheet.
Aside from being automotive rated, the DRV8801A-Q1 has a…
Hi Ivan,
Thanks for the quick response. Also we would want to know if part DRV8801A-Q1 can be used to drive linear voice coil motor? Please confirm on this.
Also I found except DRV8801A-Q1, all other TI parts are 3-Phase BLDC motor drivers. Please let…
Part Number: TPS22810 Other Parts Discussed in Thread: , DRV103 , TPL7407LA , TPS1H100-Q1 , DRV8873-Q1 , DRV8801A-Q1 , DRV8872-Q1 Hi Team
My customer wants to control 6 ~ 7V / 1A power at 20khz.
Is the TPS22810 capable of 20khz PWM control?
If not, please…
Part Number: DRV8801A-Q1
Hi Motor Drive Team,
My customer is seeing a significant inrush current when starting the the motor from cold when the motor initially tries to move with the DRV8801A.
With the current limit resistors the worst case scenario…
Part Number: DRV8802-Q1 Other Parts Discussed in Thread: DRV8801A-Q1 , Hi Team,
Can you please help me understand why there is a 1M Ohm resistor between VMx and VCP for the DRV8802-Q1? Also, how come for the same family of devices, such as the DRV8801A…
Hi Koh,
Good to see you posting on the forum.
The DRV8801-Q1 will operate properly between 8V and 12V. The nFAULT indicator is not valid during this time.
It is recommended to use the DRV8801A-Q1 for VBB <12.
OCP, OTW, and OTS are reported on nFAULT…
Other Parts Discussed in Thread: DRV8801A-Q1 Dear TI engineer
1.
MOSFET Rdson values of high side and low side are different in DRV8801A-Q1 datasheet.
Are there different mosfet high side and low side ?
2.
Ibb(q) is maximum 10uA at only 25C.
how is Ibb(q) depending…
