DRV8434A 스텝 모터 드라이버
(DRV8434A Stepper Motor Driver Carrier)
개요
- 본 제품은 DRV8434A 스텝 모터 드라이버 입니다.
- TI사의 DRV8434A 마이크로스텝핑 바이폴라 스텝모터 드라이버 칩을 탑재하고 있습니다.
- 4.5V-48V로 동작하며, 방열판 없이 대략 1.2A를 연속적으로 전달할 수 있씁니다.
- 저전압, 과전류, 과열 보호 기능을 가지고 있는 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)
- Built-in regulator (no external logic voltage supply needed)
- Can interface directly with 1.8 V, 3.3 V and 5 V systems
- Simple step and direction control interface
- 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
- Adjustable current control lets you set the maximum current output, which lets you use voltages above your stepper motor's rated voltage to achieve higher step rates
- Integrated stall detection with three GPIO pins
- Ripple control algorithm (decay mode) that allows tight regulation of current level and increased motor efficiency
- 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
- Module size, pinout, and interface match those of our A4988 stepper motor driver carriers in most respects
