Mixed, fast, and slow current-decay modes? Internal UVLO and thermal shutdown circuitry? The A includes a fixed off-time current regulator that has the ability to operate in slow, fast, or mixed current-decay modes. This current-decay control scheme results in reduced audible motor noise, increased step accuracy, and reduced power dissipation. The translator is the key to the easy implementation of the A By simply inputting one pulse on the STEP input the motor will take one step full, half, quarter, or eighth depending on two logic inputs.

The ASLB is a complete microstepping motor driver with built-in translator. The ASLB includes a fixed off-time current regulator that has the ability to operate in slow, fast, or mixed current-decay modes.

This current-decay control scheme results in reduced audible motor noise, increased step accuracy, and reduced power dissipation. The translator is the key to the easy implementation of the ASLB. By simply inputting one pulse on the STEP input the motor will take one step full, half, quarter, or eighth depending on two logic inputs. There are no phase-sequence tables, high-frequency control lines, or complex interfaces to program.

Internal circuit protection includes thermal shutdown with hyster- esis, under-voltage lockout UVLO and crossover-current protection. The pins are at ground potential and need no insulation. This classification indicates that sale of this device is currently restricted to existing customer applications. The variants should not be purchased for new design applications because obsolescence in the near future is probable.
