The TB67S569FTG(O,R,EL is a bipolar stepper motor driver IC manufactured by Toshiba Semiconductor and Storage. It features a BiCD MOS technology with PWM control, designed for driving two-phase bipolar motors. The device supports a supply voltage range of 8.2V to 44V and delivers an output current of up to 2.7A. It operates within a temperature range of -40°C to +85°C and is housed in a compact 32-VQFN (5x5mm) package.
Verify the specific suffix (O, R, or EL) against the manufacturer's datasheet to confirm packaging type and reel specifications. Ensure compatibility with the target PCB footprint for the 32-VQFN package. Confirm operating temperature requirements align with the specified -40°C to +85°C range before finalizing procurement.
Select this component for applications requiring integrated protection features such as under-voltage lockout and thermal shutdown. The 1/32 microstepping capability makes it suitable for high-precision positioning tasks. Consider the 2.7A output current limit when sizing the motor load. The compact QFN package aids in space-constrained designs.
This part belongs to Toshiba's stepping motor driver IC family, which includes variants like the TB67S559FTG and TB67S589FTG. These drivers are designed for industrial and office automation markets, offering integrated solutions that reduce external component count. The TB67S569FTG specifically targets bipolar stepper motors with moderate speed and precision requirements.
Check for direct pin-compatible substitutes within the same Toshiba series, such as the TB67S559FTG or TB67S589FTG, ensuring electrical parameters match the application needs.
