TB67S249FTG 스텝 모터 드라이버 -1.7A
(TB67S249FTG Stepper Motor Driver Carrier)
개요
- TB67S249FTG 스텝 모터 드라이버입니다.
- 마이크로 스텝핑 바이폴라 스텝모터 드라이버로 조절가능한 전류 제한 기능, 1/32스텝까지의 7 microstep 분해능을 지원합니다.
- 실제 모터 전류를 모니터링하여 optimal decay mode는 동적으로 선택합니다.
- 모터에 낮은 부하가 걸려 있을 경우는 전력과 열을 덜 내기 위해서 동작전류를 자동으로 줄여 줄 수 있습니다.
- 10V-47V의 동작전압과 1.7A (per phase)를 방열판 없이 연속적으로 전달할 수 있습니다.
- 저전력, 과전류, 과열 보호 기능이 있습니다.
특징
- Simple step and direction control interface
- Seven different step modes: full-step, non-circular half-step, circular half-step, 1/4-step, 1/8-step, 1/16-step, and 1/32-step
- Adjustable current control lets you set the maximum current output with a potentiometer, which lets you use voltages above your stepper motor's rated voltage to achieve higher step rates
- Advanced Dynamic Mixed Decay (ADMD) dynamically switches between slow and fast decay modes by monitoring the state of current decay (not according to fixed timing)
- Configurable Active Gain Control (AGC) automatically reduces drive current to minimize power consumption and heat generation when maximum torque is not needed
- Motor supply voltage: 10 V to 47 V
- Maximum continuous current per phase without additional cooling:
- TB67S249FTG: 1.7 A (4.5 A peak)
- TB67S279FTG: 1.2 A (2 A peak)
- Built-in regulator (no external logic voltage supply needed)
- Can interface directly with 3.3 V and 5 V systems
- Under-voltage lockout and protection against over-current/short-circuit and over-temperature
- Open-load detection
- Active-low error outputs indicate over-current, over-temperature, or open-load condition
- Carrier board adds reverse-voltage protection up to 40 V
- Compact size (1.0″ × 1.4″)
- Exposed solderable ground pad below the driver IC on the bottom of the PCB
