DRV8434S SPI 스텝 모터 드라이버 -가변저항 전류제한
(DRV8434S SPI Stepper Motor Driver Carrier,
Potentiometer for Max. Current Limit)
개요
- 본 제품은 DRV8434S SPI 스텝 모터 드라이버 -가변저항 전류제한 입니다.
- TI사의 DRV8434S 마이크로스텝핑 바이폴라 스텝모터 드라이버 칩을 탑재하고 있습니다.
- 4.5V-48V로 동작하며, 방열판 없이 대략 1.2A를 연속적으로 전달할 수 있씁니다.
- SPI 인터페이스를 이용하여 전류 제한, 스텝 모드(11 step modes from full-step through 1/256-step), decay mode, stall 검출 설정을 할 수 있습니다.
- 저전압, 과전류, 과열 보호 기능을 가지고 있으며, 최대 제한 전류는 가변저항으로 조절이 가능한 제품입니다.
특징
- 4.5 V to 48 V supply voltage range
- Can deliver up to 1.2 A continuous per phase without additional cooling (2 A peak)
- Can interface directly with 1.8 V, 3.3 V, and 5 V systems
- Highly configurable through SPI interface
- Optional STEP/DIR control pins (stepping can also be controlled through SPI interface alone)
- Eleven different step resolutions: full-step with 100% current, full-step with 70% current, non-circular 1/2-step, 1/2-step, 1/4-step, 1/8-step, 1/16-step, 1/32-step, 1/64-step, 1/128-step, 1/256-step
- Eight configurable decay modes, including smart tune dynamic decay and ripple control modes
- Two current limit control options available, each with two header pin assembly options, making four versions in all:
- Potentiometer for Max. Current Limit: an on-board potentiometer sets the maximum current limit up to 2 A, and the actual current limit can be scaled down through SPI
- 2A Max. Current Limit: the maximum current limit is fixed at 2A and the actual current limit is set solely through SPI in increments of 125 mA
- Integrated stall detection
- Over-temperature thermal shutdown, over-current protection, open load detection, under-voltage lockout, and charge pump over-voltage protection
- Driver IC integrates spread spectrum clocking of its internal oscillator and charge pump for reduced EMI
- 4-layer, 2 oz copper PCB for improved heat dissipation
- Exposed solderable ground pad below the driver IC on the bottom of the PCB
