TB6560AHQ/AFG: Constant-Current Chopper Stepping Motor Driver with a Micro-Step Output
The TB6560AHQ/AFG is a bipolar dual-phase stepping motor driver. Fabricated with the BiCD process, the TB6560AHQ/AFG provides large current and low ON-resistance.
Features
- Low RON (high side + low side): 0.6 Ω(typ.)
- 2-phase to 4W1-2-phase excitation
- Selectable current decay modes for improved micro-stepping
- High-speed PWM chopping at 100 kHz or higher
- The CLK input allows MCU-less motor control
- Ratings: 40 V/3.5 A (AHQ), 40 V/2.5 A (AFG)
- Wide supply voltage range: 4.5 to 34 V
- Packages: HZIP25 (AHQ), THQFP64 (AFG)
