TB67S249FTG 바이폴라 스텝모터 드라이버 모듈 -1.6A
(TB67S249FTG Stepper Motor Driver Compact Carrier)
개요
- 본 제품은 TB67S249FTG 마이크로스텝핑 바이폴라 스텝모터 드라이버 모듈입니다.
- 조절가능한 전류 제한, 7 마이크로스텝 분해능(최대 1/32 스텝까지)을 지원합니다.
- 모터 전류를 모니터링하여 동적으로 optimal decay mode 선택이 가능합니다.
- 모터의 부하가 작을 경우는 전력소비와 발열을 최소화하기 위해 자동으로 동작 전류를 줄여줍니다.
- 10V-47V의 넓은 동작 전압을 가지고 있으며, 방열판 없이 phase당 약 1.6A의 전류를 전달할 수 있습니다.
- 저전압, 과전류, 과열 보호 기능을 가지고 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) can be enabled to automatically reduce drive current by up to 40% 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: 1.6 A (4.5 A peak)
- TB67S279FTG: 1.1 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
- Compact size (0.6″ × 0.8″)
- 4-layer, 2 oz copper PCB for improved heat dissipation
- Exposed solderable ground pad below the driver IC on the bottom of the PCB
