| Part Number | A4989 |
| Manufacturer | Allegro |
| Description | The A4989 is a dual full-bridge gate driver with integrated microstepping translator suitable for driving a wide range of higher power industrial bipolar two-phase stepper motors (typically 30 to 500 W). Motor power is provided by external N-channel power MOSFETs at supply voltages from 12 to 50 V. This device contains two sinusoidal DACs that generate the r. |
| Features | ▪ 2-wire step and direction interface ▪ Dual full-bridge gate drive for N-channel MOSFETs ▪ Operation over 12 to 50 V supply voltage range ▪ Synchronous rectification ▪ Cross-conduction protection ▪ Adjustable mixed decay ▪ Integrated sinusoidal DAC current reference ▪ Fixed off-time PWM current control ▪ Enhanced low current control when microstepping ▪ Pin compatible with the A3986 PACKAGE: 38 pin TSSOP (suffix LD) Approximate footprint DESCRIPTION The A4989 is a dual full-bridge gate driver with integrated microstepping translator suitable for driving a wide range of higher power industria. |
