Texas Instruments’ TIDA-00447 is a 24 V reference design for controlling two brushless DC (BLDC) motors in appliance pump and fan applications. It combines a 100 W continuous, discrete motor-drive stage with a 30 W continuous stage built around an integrated driver. Both are sensorless, but they use different control methods and target different power levels.
What TIDA-00447 is designed to do
The design addresses appliance systems that need separate motors, such as a dishwasher’s circulation and drain pumps. TI’s design page describes the two stages as 100 W and 30 W continuous, with circulation-pump and drain-pump examples, respectively. These ratings describe the reference design; they do not establish that either stage suits every motor at that power.
“Sensorless” means the drive estimates rotor position from electrical behavior rather than relying on a separate position sensor. TIDA-00447 does not use one common control approach for both motors: the higher-power stage uses sensorless trapezoidal control, while the lower-power stage uses sensorless sinusoidal control. Texas Instruments’ TIDA-00447 page identifies the design components and operating approach.
How the 100 W and 30 W stages differ
| Stage | Example use and rating | Power-stage implementation | Sensorless control | Other published details |
|---|---|---|---|---|
| Higher-power | Circulation pump; 100 W continuous | Discrete MCU, external MOSFET driver, current sensing, and external power MOSFETs | InstaSPIN-BLDC trapezoidal control using back-EMF integration | TI says the discrete approach allows drive power to be scaled. |
| Lower-power | Drain pump; 30 W continuous | Integrated three-phase driver with power MOSFETs | Sensorless sinusoidal control | 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. |
The two stages are not interchangeable just because both are 24 V and sensorless. Compare the target motor and appliance requirements, continuous power, control method, scalability, external-component count, and required protection before adapting either implementation.
#1 Best Overall
- 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 TI says was tested
TI states that TIDA-00447 was fully tested for full-load operation, overcurrent protection, and motor-stall protection. This is the stated test scope for the reference design, not a certification or a guarantee that a derivative design will behave the same way. Changes to the motor, layout, components, firmware, or operating conditions can affect performance and protection behavior.
Where to find the design files and firmware
TI lists a design guide, assembly drawing, bill of materials, CAD/CAE symbol archive, Gerber files, PCB layout, and schematic on the TIDA-00447 design page. The linked guide is Rev. B, dated May 12, 2016; its date is document metadata, not evidence of a recent release.

- 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.
The firmware is listed separately as TIDCBC1 version 01.00.00.00, with a release date of October 29, 2015. TI notes that its download resource has been migrated. Confirm the current download availability and review the documentation before basing a new design on these historical files.
