Packaging & ESD

Industry-standard static shielding packaging is used for electronic components.Anti-static, light-transparent materials allow easy identification of ICs and PCB assemblies.
The packaging structure provides electrostatic protection based on Faraday cage principles.This helps protect sensitive components from static discharge during handling and transportation.


All products are packed in ESD-safe anti-static packaging. Outer packaging labels include part number, brand, and quantity for clear identification. Goods are inspected prior to shipment to ensure proper condition and authenticity.

ESD protection is maintained throughout packing, handling, and global transportation. Secure packaging provides reliable sealing and resistance during transit. Additional cushioning materials are applied when required to protect sensitive components.

Frequently Asked Questions

TC78B009FTG can I directly replace my existing BLDC motor driver IC without modifying the firmware or hardware layout?
Direct replacement depends on interface compatibility and current requirements. The TC78B009FTG uses I2C and PWM control, supports a 5.5V to 27V supply range, and delivers up to 240mA output. If your current driver operates within these voltage and current limits and uses the same control signals, it may be compatible. However, verify gate drive timing, phase sequencing, and thermal performance in your application before assuming drop-in replacement.
What are the key differences between the TC78B009FTG and similar Toshiba models like the TC78B008FTG that affect motor control design?
The TC78B009FTG differs from earlier versions primarily in improved noise immunity, tighter timing tolerances for commutation, and enhanced I2C communication stability at higher temperatures. Unlike the TC78B008, the FTG version includes better ESD protection on I/O pins and supports extended industrial temperature ranges (-40°C to 105°C), making it more suitable for harsh environments. These changes require careful evaluation of PCB layout and signal integrity.
Can the TC78B009FTG operate reliably in high-vibration industrial automation equipment?
Yes, the TC78B009FTG is qualified for industrial applications with an operating temperature range of -40°C to 105°C and MSL 3 compliance. Its surface-mount 36-WQFN package provides good mechanical stability when properly soldered with sufficient pad reinforcement. However, long-term reliability under vibration depends on board design, solder joint quality, and thermal management—ensure adequate creepage and clearance per IPC standards.
How should I configure the I2C interface on the TC78B009FTG when integrating with a microcontroller that has limited pull-up capability?
The TC78B009FTG’s I2C interface requires external pull-up resistors on SDA and SCL lines. For microcontrollers with weak internal pull-ups (typically >10kΩ), use 2.2kΩ to 4.7kΩ resistors matched to your bus speed and trace capacitance. At 100kHz operation, keep total bus capacitance below 400pF. Place pull-ups close to the TC78B009FTG to minimize EMI and ensure clean signal edges during motor switching transients.
Is it safe to operate the TC78B009FTG near its maximum current rating of 240mA in continuous duty cycles?
Continuous operation at 240mA requires strict attention to thermal conditions. The 36-WQFN package has an exposed pad for heat dissipation, but junction-to-ambient thermal resistance must be evaluated using PCB copper area and airflow. In confined enclosures or without forced cooling, sustained loads above 200mA may cause thermal throttling or reduced lifespan. Always simulate or measure junction temperature under actual load profiles.
What precautions should I take when migrating from a bipolar transistor-based BLDC driver to the TC78B009FTG?
Transitioning from discrete components to the TC78B009FTG simplifies design but introduces new considerations. Ensure your power stage MOSFETs have threshold voltages compatible with the TC78B009FTG’s NMOS architecture. Validate commutation timing, dead-time settings via I2C, and PWM frequency alignment with motor inductance. Also confirm that gate drive voltage levels meet the controller’s specifications to avoid shoot-through or slow switching.
Can the TC78B009FTG support sensorless back-EMF detection for low-speed BLDC motor control?
No, the TC78B009FTG is designed for sensored BLDC motor control only. It does not include built-in back-EMF zero-crossing detection circuitry. For sensorless applications, alternative controllers with integrated Hall emulation or BEMF sensing are required. Attempting to use the TC78B009FTG without position sensors will result in uncontrolled commutation, especially below 5–10% rated speed.
How does the TC78B009FTG handle overcurrent protection during startup inrush conditions?
The TC78B009FTG includes internal current limiting and fault reporting via I2C status registers. During startup, if motor current exceeds safe thresholds, it triggers a soft shutdown and sets a fault flag. Designers must implement software delays after power-up and monitor fault states to prevent nuisance trips. Additionally, consider adding external snubbers or soft-start algorithms to reduce inrush current spikes.
Are there any known limitations when using the TC78B009FTG with high-inductance DC motors?
High-inductance motors can cause slower response times and increased switching losses with the TC78B009FTG due to its fixed PWM frequency and limited gate drive strength. While the device can drive such loads safely within current limits, expect reduced efficiency and potential audible noise at low speeds. Evaluate motor time constants against the controller’s commutation update rate and consider adding RC filters or adjusting PWM dead zones if ringing occurs.
What are the implications of using the TC78B009FTG in battery-powered portable devices?
In battery-powered systems, the TC78B009FTG’s quiescent current and switching efficiency significantly impact runtime. With typical quiescent current around 10µA and efficient NMOS half-bridge design, it offers reasonable power savings. However, disable unused features via I2C and use dynamic PWM scaling to match load demand. Also account for voltage sag during motor acceleration—ensure minimum operating voltage remains above 5.5V throughout discharge cycle.
