TB67S128FTG 스텝 모터 드라이버
(TB67S128FTG Stepper Motor Driver Carrier)
개요
- 본 제품은 TB67S128FTG 스텝 모터 드라이버 입니다.
- TB67S128FTG 마이크로스텝핑 바이폴라 스텝모터 드라이버 칩을 탑재하고 있습니다.
- 조절가능한 전류제한 및 1/128 스텝을 지원합니다.
- 모터 전류를 모니터링하여 optimal decay mode를 동적으로 선택할 수 있습니다.
- 모터에 부하가 적을 경우 동작 전류를 자동으로 줄여 줄 수 있습니다.
- 6.5V-44V 의 동작전압을 가지고 있으며 연속적으로 2.1A를 전달할 수 있습니다.
- 저전압, 과전류, 과열보호 기능을 가지고 있습니다.
- 최대 40V까지 역극전압 보호 기능을 가지고 있습니다.
특징
- Two interface modes to select from:
- clock mode for simple step and direction control
- serial mode for controlling the driver's many features through a serial interface (this mode also allows for serial control of the current limit)
- Eight different step modes: full-step, half-step, 1/4-step, 1/8-step, 1/16-step, 1/32-step, 1/64-step, and 1/128-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
- Four different decay modes: mixed decay (two timing ratios), fast decay, or Advanced Dynamic Mixed Decay (ADMD), which 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: 6.5 V to 44 V
- Can deliver up to approximately 2.1 A per phase continuously (5 A peak) without additional cooling
- Can interface directly with 3.3 V and 5 V systems
- 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
- Carrier board breaks out all of the TB67S128FTG pins in a compact size (1.2″ × 1.6″)
- Exposed solderable ground pad below the driver IC on the bottom of the PCB
