Drawing on Trinamic’s expertise in motion control technology, ADI has developed a comprehensive portfolio of motion control chips covering four key areas: BLDC (brushless DC) motor drivers, motor encoder decoding, integrated smart motor drive and control solutions, and stepper motor drivers. These are suitable for applications such as humanoid robots, industrial automation, AGVs/AMRs, medical equipment, semiconductor equipment, whilst incorporating core capabilities such as quiet operation, high-precision closed-loop positioning, hardware FOC and multi-protocol feedback decoding. These components are frequently stocked for industrial projects and robotics solutions.

I. Brushless DC Motor (BLDC/PMSM) Driver Solutions

ADI’s BLDC drivers are centred on hardware FOC (Field-Oriented Control), which, unlike traditional software FOC solutions, embeds the position, speed and torque loop controllers within the hardware itself. This significantly frees up computing power on the main control MCU, making them particularly well-suited for multi-joint, servo-intensive applications such as humanoid robots and automated equipment. A representative model, the TMC9660, supports a wide input voltage range of 8V to 70V, with a continuous phase current of 10A RMS and a peak current of 20A. It also supports both braking choppers and electromechanical braking outputs, and can be paired with ABN incremental encoders or Hall sensors for position feedback. With SPI/UART communication interfaces, a single chip is capable of performing closed-loop servo control for a three-phase permanent magnet synchronous motor. Additionally, the TMC6460 micro FOC driver is designed for micro hollow-cup BLDC motors. With its compact package and support for daisy-chain cascading, it is well-suited for dexterous grippers and micro-servo modules.

The series’ key advantages lie in its low noise, high dynamic response, and comprehensive diagnostic protection against overcurrent, overtemperature and overvoltage; It supports both sensorless FOC and sensor-based closed-loop modes, and is widely used in AGV wheel drives, conveyor line servos and drone gimbals. The products are primarily available in QFN, TQFN and PQFP packages.

II. Motor Encoder and Decoder Solutions

ADI’s encoder product line is divided into two main categories: magnetic sensor encoder chips and multi-protocol encoder decoder chips, which serve as the core feedback components for motor position closed-loop control.

The TMC8100 is a multi-protocol absolute encoder decoder chip that natively supports mainstream industrial protocols such as SSI, BiSS-C, EnDat and Tamagawa, whilst also supporting the reception of incremental ABN encoder signals. Its high-speed 25 MHz SPI interface eliminates the need for FPGA decoding development, thereby reducing the BOM cost of servo systems; it is frequently used in conjunction with the TMC9660 and TMC6460 as part of a driver system, and is the standard feedback solution for humanoid robot joint servos. The ADMT4000 is a GMR+AMR magnetic encoder with a typical angular accuracy of ±0.25°. It supports multi-turn absolute position recording, requires no zero-return upon power-up, and retains position data in the event of a power failure, making it suitable for low Earth orbit satellite mechanisms and precision medical equipment where high reliability is essential.

III. Smart Motor (Integrated Drive and Control Servo) Solutions

ADI’s smart motor solution is essentially a highly integrated servo controller combining drive, control and feedback interfaces—commonly referred to as a single-chip smart servo—eliminating the need for an additional external motion control MCU.

These products integrate FOC algorithms, microstep interpolation, load detection, encoder interfaces and communication interfaces onto a single chip. They possess autonomous position planning and the ability to generate acceleration and deceleration ramps; the host controller need only issue target position commands, without the need for real-time intervention in the current and speed closed-loop control. The TMC9660 and TMC6460 both belong to the intelligent drive-and-control platform and are paired with the TMCL host software for rapid parameter tuning.

In terms of applications, they are primarily used in humanoid robot joints, collaborative robots and small servo modules; some modular smart motor products also utilise chips from this series.

IV. Stepper Motor Driver Solutions

ADI’s stepper drivers are renowned in the industry for their quiet operation. Core technologies include StealthChop2 silent chopping, SpreadCycle high-dynamic chopping, StallGuard sensorless stall detection, and CoolStep adaptive power saving, which address the pain points of traditional stepper motors such as high noise, excessive heat generation and difficulty in detecting missed steps. Key models include the TMC2241, TMC5130 and TMC2660.

The TMC2241 is a 65V, 3A two-phase stepper driver offering up to 256 microsteps of resolution. It features built-in lossless current sensing and is housed in a compact TQFN38 package, making it suitable for 3D printing, CNC machinery and inspection equipment; The TMC5130 is an integrated driver and controller with a built-in position generator, capable of performing point-to-point motion independently; the TMC9660 is compatible with both two-phase stepper motors and three-phase BLDC motors, covering both motor types with a single chip, making it suitable for multi-axis hybrid control designs in equipment.

Stepper drivers are widely used in automation platforms, optical stage systems and semiconductor inspection equipment.

V. Electronic Component Recycling Process

Shenzhen Mingjiada Electronics Co., Ltd. provides electronic component recycling services. Items accepted for recycling include factory offcuts, cancelled project stock, surplus stock held by distributors, and idle ICs from design houses. The materials accepted for recycling are primarily genuine products that are in their original, uninstalled condition, with intact reel or tube packaging and clearly identified batch numbers. The complete process is as follows:

1. Submission of Bill of Materials

Customers organise the materials to be recycled, clearly labelling the model, brand, quantity, package type, batch number and packaging condition, and attach photographs of the physical items and reel labels. These are then sent to the evaluation team via email or online channels.

2. Professional Assessment and Quotation

Assessment engineers verify the items against real-time semiconductor market prices, model scarcity, packaging integrity, year of manufacture, and whether they are automotive-grade or industrial-grade. As market prices fluctuate significantly, a formal recycling quotation is generally provided within 24 hours; for small batches, samples may be sent for verification, whilst for large batches in the Pearl River Delta region, on-site inventory checks are supported.

3. Transaction Confirmation and Agreement Signing

Once both parties have reached a mutual agreement, a purchase and sale agreement is signed, clearly specifying the part numbers, quantities, unit prices, delivery methods and settlement cycles to lock in prices and mitigate the risk of market fluctuations; at the same time, a distinction is made between recyclable materials and non-recyclable materials (such as refurbished, board-disassembled, moisture-damaged, oxidised or counterfeit items).

4. Material Delivery and On-Site Verification

The client dispatches the goods or Mingjiada arranges for collection on-site. Upon receipt into the warehouse, each reel is checked against the model, silkscreen marking, batch number and packaging; the materials are inspected for oxidation, pin damage, moisture damage or re-taping. Once the verification results match the initial list, the settlement process commences.

5. Payment Settlement and Transaction Closure

Upon successful verification, payment is made via the agreed method. We support various settlement options, including corporate and personal accounts; for large-volume stock, cash-on-delivery is available. Once the transaction is complete, compliant materials undergo re-inspection, re-taping and warehousing before entering Mingjiada’s spot supply channel, where they are distributed to automation and robotics customers with demand, thereby facilitating the circular flow of components. Non-compliant materials are disposed of in accordance with industry standards and are not released onto the market.
