For Single Phase BLDC control, it seems that TI does not provide many reference designs…
Part Number: DRV8701EVM Other Parts Discussed in Thread: TIDA-00875 , DRV8870 HI,
I have read the reference design TIDA-00875.
And I have used the DRV8870 to drive the single-phase BLDC.
But I had a problem with the motor starting itself in certain…
Hi Frank,
Take a look at this reference design: TIDA-00875. You should be able to accomplish a very simple single phase design using an H-Bridge driver with a PH/EN interface and an external hall sensor (i.e. DRV5013). The DRV8876 or DRV8801 should…
Timur,
Is is a 3-phase BLDC fan or a single-phase BLDC?
If single phase, then yes you could drive 2x fans with DRV8426P. Or consider a single h-bridge driver like the DRV8876 (upgrade to DRV8801A mentioned in TI design).
Please see TI design for…
Hi Shivam,
Thank you for your interest in TI products.
Are you interested in using the Hall sensor for rotary encoding or motor commutation? What is the typical speed of this motor in your application?
A Hall-effect latch is the correct type of…
Hi Ann,
If you are referring to a brushed motor and an electrically commutated (EC) brushless motor with a single hall sensor, there is no difference.
As an example, please see the reference design:
If you are referring to 3 phase brushless design…
Brian,
The DRV8701, DRV8702-Q1, DRV8702D-Q1, DRV8703-Q1, and DRV8703D-Q1 are our closest devices. Speed control and hall-sensor feedback may need to be controlled by external circuitry. We do not integrate those features in these devices.

Part Number: DRV8801 Other Parts Discussed in Thread: TIDA-00875 , Hi,
One of my customer designed a single phase BLDC operated on 12V using DRV8801 with reference from TIDA-00875.
1. When i try to stop the fan blades physically using some obstacle…
Hi Diederik,
The BG3612 EC motor needs the phases to be changed based on the hall inputs. A brushed dc driver with a full bridge or a BLDC driver with three half bridges can perform this function.
Please see www.ti.com/.../TIDA-00875 as an example…
