Texas Instruments’ TIDA-00447 is a 24 V reference design for controlling two brushless DC (BLDC) motors, with separate 100 W and 30 W stages intended for appliance pumps and similar fan or pump applications. The higher-power stage uses a discrete sensorless trapezoidal drive; the lower-power stage uses an integrated driver and sensorless sinusoidal control. TI developed the assembled board for testing and performance validation, not for sale.
What TIDA-00447 is built to do
The design pairs two motor-drive stages on one 24 V reference platform. TI presents a circulation pump as the 100 W stage’s example load and a drain pump as the 30 W stage’s example. Pump and fan applications are the intended context; the ratings alone do not establish that either stage suits a particular motor or appliance.

Sensorless control means the drive does not rely on a rotor-position sensor for the control approach described here. The two stages use different control methods and power-stage implementations, so they should be treated as distinct design choices rather than interchangeable outputs.

How the 100 W and 30 W stages differ
| Stage | Example application and rating | Power stage and control | Other published details |
|---|---|---|---|
| Higher-power | 100 W continuous; circulation pump | Discrete microcontroller, external MOSFET driver, current sensing and external power MOSFETs. InstaSPIN-BLDC provides sensorless trapezoidal control using back-EMF integration. | TI says the discrete approach makes it possible to scale drive power. |
| Lower-power | 30 W continuous; drain pump | Integrated three-phase driver with power MOSFETs and sensorless sinusoidal control. | An integrated buck/linear regulator supplies 5 V or 3.3 V. TI describes a low external-component count and overcurrent, voltage-surge, UVLO and motor-lock protection. |
These are TI’s published design specifications, not a claim that the motors, loads or stages can be swapped without further engineering. Compare a candidate implementation against the motor’s electrical requirements and the appliance’s operating conditions, protection needs, and desired power scalability.

- Product Parameters: BLDC brushless control board wide voltage 6-60V, high power 400W, DC three-phase brushless hall controller, support for PLC 0-5V touch volume control, support for PWM control, amplitude 2.5-5V. This driver is only applicable to the electric angle of 120 degrees of DC brushless hall motor
- Note: Brushless motors also generally have five Hall wires or interfaces. Two of them are hall power supply line, three are hall signal line, to distinguish especially hall power supply line. Three Hall signal lines are generally labeled a b c, the driver board also has ha Hb Hc three ports and other similar characters, respectively, corresponding to connect
- Features: MA MB MC phase line output motor. 5V GND The mainboard comes with a 5V power supply. VCC GND Main power supply. SC speed pulse signal output. DIR Direction control Forward/reverse control interface. STOP Stop the control interface. BRAKE Brake control Indicates the brake control port. Speed control Input speed control signals. Ha Hb Hc +5V GND Hall signal power supply input interface. Generally, the motor with Hall has the corresponding 5 wires
- Note: This controller requires hall to function. If your motor doesn't have a hall then it won't work. The brushless motor application scenarios are very wide, such as electric vehicles, drones, fans, range hoods
- Package: The product comes with 2pcs of Brushless Motor Controller and wires
What the control and integration choices mean
Discrete 100 W stage
The higher-power implementation separates the microcontroller, gate-driver function, current sensing and power MOSFETs. TI identifies this architecture as a way to scale drive power. That flexibility comes with a more distributed implementation than the integrated lower-power stage; the source does not quantify a cost, efficiency or board-area advantage.
Integrated 30 W stage
The lower-power stage combines the three-phase driver and power MOSFETs, with sensorless sinusoidal control. Its integrated regulator provides a 5 V or 3.3 V supply, and TI describes the design as requiring few external components. Its listed protection functions include overcurrent, voltage surge, undervoltage lockout (UVLO) and motor-lock detection.
Rank #2
- 3-Phase BLDC Motor Compatibility & Core Specs：This controller operates exclusively with 120° electric angle 3-phase brushless DC motors equipped with Hall sensors. It supports a 6-60V DC input, delivers 200-300W rated power (350W peak) with 16A continuous (20A peak) output, and enables PLC-compatible 0-5V analog or PWM (2.5-5V amplitude, 50Hz-20kHz frequency) speed control—ideal for DIY robotics, small electric tools, brushless pumps, cooling fans, and industrial automation setups.
- Multi-Mode Speed & Direction Control：Adjust speed via the on-board potentiometer, external 0-5V analog input, external potentiometer, or PWM signal. It integrates forward/reverse, stop, and brake functions: note that forward/reverse and brake operations use hard commutation, so reduce speed throttle to below 50% before activation to protect power components from damage.
- Practical Design & Safety Guidelines:Features terminal block interfaces for easy wiring and a standard heat sink for stable heat dissipation. Built-in overcurrent protection safeguards the motor output; the main power circuit lacks a fuse, so external fusing is recommended. Reversing DC power polarity will permanently damage on-board chips, even under brief high-current conditions.
- Safe Initial Testing & Wiring Troubleshooting:For first use, test with low voltage (7-12V) and low current (1-3A) to validate wiring. If the motor jitters, fails to start, or runs in one direction only, adjust the sequence of the 3 motor phase wires (6 possible combinations, only one correct) to resolve mismatches—avoid high-current/high-voltage testing during troubleshooting to prevent module damage.
- Wide Application Scenarios:Suited for a range of projects: DIY robotics and model vehicles, small electric tools (mini drills, grinders), industrial automation (conveyors, lab mixers), fluid equipment (brushless water pumps, fans), and PLC-controlled systems, offering reliable speed regulation for brushless motor setups.
Validation claims and their limits
TI says it tested TIDA-00447 for full-load operation, overcurrent protection and motor-stall protection. This describes the reference design and the stated test scope; it is not a certification, a guarantee for an appliance, or evidence that a modified or derivative design will pass the same tests. A product implementation still needs validation against its own motor, load, power supply, thermal conditions and applicable requirements.
Where to find the schematic, BOM and firmware
TI’s TIDA-00447 design page lists downloadable design resources, including the design guide, assembly drawing, bill of materials (BOM), CAD/CAE symbol archive, Gerber files, PCB layout and schematic. The official page lists the guide as Rev. B, dated May 12, 2016. These files support study or reproduction of the design; check the page for the current download links and resource availability.

TI also lists firmware TIDCBC1, version 01.00.00.00, with a release date of October 29, 2015, and notes that the download resource has been migrated. DRV10983 is the integrated control BLDC driver named in the design; it is a component, not the complete two-motor reference design. Component lifecycle and availability can change, so verify current details with TI before selecting parts.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Can you buy the assembled board?
No. TI states that the fully assembled TIDA-00447 board was developed for testing and performance validation only and is not available for sale. The practical route for examining the implementation is to use the documentation and design files on TI’s page, then assess and validate any hardware built from them for its intended application.
